New Account created in error by AT&T but I'm charged for it when my phones were already covered under the original account when purchased.

I have tried more than 6 times to resolve a billing issue that was created in error by AT&T. Now I'm being billed by a collection agency to collect on a balance of $92.22. I was told and received by AT&T reps multiple times that the issue was resolved.

Account XXXXXXX2768 was created in error and the charges were not valid. I even phone conferenced with an AT&T rep and the collection agency to resolve. Yet today, again, I have received an email from the collection agency indicating that I still owe the fee because of the contract that I signed when I first purchased phones and services with AT&T years ago.

The AT&T reps admitted they created the account in error and placed notes in their system to the effect. I have spoken with multiple departments including customer care, fraud, collections, billing, and mobility on numerous times.

I should not have to pay almost a hundred dollars for an error that was created internally by AT&T.

I will keep pursuing this issue until it's resolved to my satisfaction and I don't receive any more collection notices.

If the strategy is to wear a customer down until they capitulate and pay money for something they didn't order, request or use, then it's not working with me. Buyer BEWARE!!!!
