Fraud

Call their Global Fraud Management back (make sure you are calling the correct number). If that still gets dissmissed, file a BBB complaint as that goes to the corporate level.

Report an unauthorized AT&T account or an account change

what are their hours I need to contact them ASAP

My understanding is they have traditional business hours. Likely closed right now, but you can call and see if you can leave a message or get a confirmation of what the hours are. If nothing else, call tomorrow after either 6 or 8 EST would be a safe bet.

Thank you and they should get the problem sorted out before it affects my credit score 

The AT&T Global Fraud department is a fraud! We take our valuable time to submit an online complaint and in a matter of days it is dismissed without an investigation or explanation for their findings. I don’t know how this company is allowed to operate in this manner. Yes, contact the BBB because I can tell you, you will not get a resolution and your credit will be negatively impacted even though you did not authorize the charges in the first place. The fraud department is a joke and a scam and has only been implemented to deter and frustrate loyal customers.

@Drelly I believe I can tell you exactly why your case was dismissed without any investigation. If your complaint was about the phone and phone line added to your account two years ago as you described in your other post, as I predicted, you are going to have a very difficult time convincing anyone the line wasn’t authorized two years later.

@Drelly 

AT&T like practically any company expects to be notified within a reasonable time if there is a billing issue or other dispute. Going 2 years before you noticed an extra phone line on your account makes it look like you are trying to scam them.

Sorry but their Global Fraud department is not a fraud as you accuse. You simply left a problem go far beyond any reasonable time frame to dispute. Consider the money of that line your cost of the lesson that it is your responsibility to manage your finances and bills and not expect companies to personally review them each month for you.
