charged AT&T K006 9986 ESTOR

On the 8/2/2016 I just got the same charged AT&T K006 9968 Estor for $617.29, my bank will refund the money however the moral to the story was that every times my husband and I  called AT&T to get details to the of what was charged on our account. It seem like no one/any employee at AT&T couldn't help nor provided us any useful information and kept directing us to different departments due to  lack of knowledge of the company as a whole.  Obviously, the transaction was being made by AT&T, if AT&T does not know what is being charged and how to track each of your own (AT&T) Transactions. How did your consumes trusted your business? Lucky we are not your customer and we know this charged was fraudulent. How are you (AT&T-company) going to deal with the fraud? Are you protection your consumers identity? The reason why I asked all these question my card that was being changed the billing address that they provided you does not matched with the current billing address because we had moved several months ago.  We also got charged at Walmart.com on the same day but for some reasons Walmart does a lot better job than AT&T. Walmart was able the resolved the issued and stop the order process .  Please don’t send me the genetic letter and wasted your time on the letter, just put your time how you can track your transactions better and we know that so many are also effect by this fraudulent charged.
