I have been a victim of this "cramming" for the past several months as well. AT&T was not helpful until I really got tough with them. They at first said I had to contact the company who placed the charges in order to get my refund. I tried to contact the company, and of course, you get put on hold forever and never get to speak to a real person. So, I called AT&T back and demanded that they give me credit and put a 3rd party block on my phone bill. They did. Unfortunately, however, fraudulent charges were made again the next month, and the next month. So I had to go around and around with all parties involved several times. What is insane is that these charges were made in my husband's name, whose name is not even on the account. Once, when we were moving, my husband tried to call the phone company to change our service to our new address. They said they could only talk to me because my name was on the account. But these scammers can make fraudulent charges under my husband's name??? It is insane and infuriating! I tell you, if this happens again, Vonage is just a phone call away!!
P.S. Like others, I have taken my bill off of auto-pay until this mess is cleared up.
