I had a third party charge on my AT&T bill. When AT&T was asked why they allow this without any written authorization, the answer is that they "assume" the charge is legitimate because this third company has all our information! AT&T said they can't do anything to stop and that I had to call the number on the bill: 1800 4...
When I called this number they gave me a name of someone who works for us (incorrect spelling by the way), and said this person requested the service, which is absolutely not true. This person who works for us did receive several telemarketing phone calls the week before the charge, but never actually requested anything.
The scam company made me send them an email with ALL my information before they refund the money (I still have not seen the refund on my bill); name. address, phone number, etc... I wonder in which other scam list my information is going to end up.
