When you see 833-401-2052 on your caller ID, know that the call is from Maury Cobb Attorney at Law LLC, a debt collection law firm.
The reason they’re calling is to collect a debt, probably owed to T-Mobile. But don’t respond until you understand who they are and what your rights are.
Maury Cobb Attorney at Law is a debt collection law firm in Birmingham, Alabama. They don’t lend money or extend credit. All they do is collect debts on behalf of original lenders.
It can be intimidating to get a call from a law firm. We tend to respect and trust authority, and a call from a lawyer’s office implies the possibility of a lawsuit if you don’t pay up. Calls from typical collection agencies don’t carry the same implied threat.
So who is Maury Cobb Attorney at Law, exactly? Here’s what we found in public records:
Full Name: Maury Cobb, Attorney at Law, LLC
Type of Entity: Collection law firm; third-party debt collector
Date Founded: October 2013; started doing business January 2014
Address: 600 Beacon Parkway West, Suite 300B, Birmingham, AL 35209 O
wner: Richard Maury Cobb; admitted to practice law in Alabama by the Alabama State Bar since 2012
Affiliations: AmSher Collection Services, Inc.
Better Business Bureau (BBB) Rating: F (not accredited); 129 complaints
Prominent Client: T-Mobile (also represents Charter/Spectrum, Dish Network, and Synovus Bank)
You’re not the only one who’s been frustrated by this debt collection firm. There are at least 111 complaints filed against the company in the Consumer Financial Protection Bureau (CFPB) complaint database.
In addition, 129 complaints have been logged on the BBB website, which has assigned the company an F rating. We found at least 20 federal lawsuits naming the company as a defendant, including three class actions alleging Fair Debt Collection Practices Act (FDCPA) violations.
In one of these class actions, entitled Gomez v. Maury Cobb Attorney at Law LLC, the plaintiff alleged that the firm’s collection letters featured settlement offers with response deadlines that fell before the end of the 30-day debt validation period required by law. This pressured consumers to make a payment before they had the chance to dispute the debt.
Why Are They Calling You?
They probably represent T-Mobile or another company that thinks you owe it money. Here’s how that probably happened.
The company that T-Mobile hired to collect from you, AmSher, decided to escalate your account to their go-to law firm, Maury Cobb. They probably did this because they were unable to get anywhere with you over the phone, and thought that getting a law firm involved would light a fire under you.
If the original creditor charged off your debt, which is likely if your account was placed with a collection law firm, they have already written it off as a loss and claimed a deduction on their taxes. This is important because it means that they’re not even losing money if you never pay.
The further your debt is from the original creditor, the more likely it is to have missing paperwork or other documentation problems. If the debt collector can’t document your debt adequately, you shouldn’t have to pay it.
Red Flags Associated with Calls from 833-401-2052
There are some big red flags associated with calls from 833-401-2052.
They Won’t Identify the Company Unless You Tell Them Who You Are
This is one of the most common complaints about the calls from 833-401-2052.
One consumer reported the following on the Should I Answer website: “Was a live person saying they were from some atty office trying to collect a debt. Wanted me to verify information, I refused saying I wasn’t verifying anything until they told me who they were. Which they refused to confirm.”
This is a huge red flag. Debt collectors are required by the FDCPA to identify themselves.
If someone calls you, demanding your date of birth without explaining who’s calling and why, don’t give them the information. Never give out sensitive financial information to someone who you can’t verify is who they claim to be. You might not even owe the debt. Wrong-number calls and cases of mistaken identity are common with this company.
Here’s what one consumer filed as a BBB complaint in September 2025: “Fraudulent business keeps calling me for a debt under a name similar to mine but misspelled by one letter.”
Here’s what another consumer told the website 800Notes: “This number leaves me text messages on my spare cell phone. I don’t have any debt and the number was just assigned to my spare cell phone.”
If a debt collector is trying to collect someone else’s debt from you, you shouldn’t have to pay it, and any credit report entry they place is eligible for dispute.
What Other Consumers Have to Say About Calls from 833-401-2052
They Call at an Alarming Rate and at Bad Hours
The frequency and timing of calls from this number routinely cross the line from persistent to abusive.
Here’s what one consumer reported on Should I Answer: “I GET CALLS AT 6AM. THEY CALL UP TO 3 TIMES A DAY AND NO VOICEMAIL.”
Here’s what someone else filed as a CFPB complaint: “More than 30 calls. Requested they stop calling.”
Calling before 8:00 a.m. or after 9:00 p.m. in the consumer’s time zone, or calling so frequently or in such a manner to harass, is prohibited by the FDCPA. These are concrete, enforceable rights that exist for the specific purpose of preventing this exact kind of behavior.
They Ignore Requests for Debt Validation
In October 2025, a consumer filed the following complaint with the BBB: “I have paid my debt in full to T Mobile and have received confirmation that I owe them no money. This company is on my credit report attempting to collect the same debt.” The consumer continued: “I specifically asked a representative to provide me with detailed debt validation information. This request was completely ignored.”
If a debt collector ignores your request for validation, they lose the legal authority to pursue the debt further. This is a basic right under the FDCPA, and ignoring it is the exact kind of procedural mistake that can make a credit report entry vulnerable to dispute.
How to Stop the Calls from 833-401-2052
To stop the calls from 833-401-2052, you need to dispute the credit report entry they placed.
Challenging a credit report entry is the most effective way to deal with an unwanted debt collection. When you dispute a credit report entry, the credit bureau is legally required by the FCRA to conduct an investigation.
At that point, the debt collector has 30 days to validate your debt completely. This is where documentation problems can become your friend. Every time your debt changes hands, the chain of title and supporting paperwork can get lost or incomplete. Collectors aren’t going to spend more than your debt is worth to verify it.
Time Is on Your Side
There are a couple of reasons why time is on your side.
Every state has a statute of limitations on debt collection that specifies how long a creditor or debt collector can sue you over a debt. Once the statute of limitations runs out, the debt is no longer enforceable in court.
This is another silent ally that you have on your side. With every month that passes, your statute of limitations grows stronger. This is why collection agencies are so heavy-handed on the phone. They know that the older a debt gets, the less leverage they have. The phone calls are designed to create a sense of urgency because that’s what they’re losing.
Three Federal Laws That Protect You
There are three federal laws that you need to understand.
The FDCPA, FCRA, and TCPA are the three federal laws that protect you from bad debt collectors. The FDCPA outlaws abusive behavior from third-party debt collectors, like harassment, false statements, and unfair practices. The FCRA requires that every entry on your credit report be substantiated and accurate. The TCPA restricts the use of robocalls without your consent.
Here’s what the public data says about 833-401-2052: nomorobo.com: confirmed robocaller TelGuarder: 28 complaints; 92.9 percent caution index CallFilter.app: 8 negative out of 9 reviews Each of these data points may represent a potential TCPA violation that can be used to support a credit report dispute.
These Laws Aren’t Just Shields — They’re Swords, Too
Most consumers think of their legal rights as defensive tools, but they can also be offensive tools. A well-documented dispute can force the debt collector to prove its case, and in many cases, the collector can’t.
When a company has 129 BBB complaints, 111 CFPB complaints, and several class actions accusing it of the same types of violations, it’s a good bet that they’re not operating aboveboard. The question is whether you’re going to use your rights or not.
What’s Happening with Calls from 833-401-2052
In conclusion, what’s happening with calls from 833-401-2052 is simple.
The calls aren’t going to stop unless you take action on the credit report side. Blocking the number might make the calls stop temporarily, but it won’t address the underlying credit report entry. If Maury Cobb Attorney at Law can’t validate your debt or provide complete documentation, the entry shouldn’t be on your credit report. A formal dispute is how you can force the issue.
