Overcharged or wrongly billed by AT&T and would like to dispute? Try this.

Yes, I shouldn't have been charged but AT&T somehow did.

Yes, it should be impossible but AT&T somehow made the impossible possible. I had a number under my multi-line account and removed that number. In addition, i turned off the autopay on my main account. When I reactivated auto-pay, the number that was removed became a separate account without my consent and AT&T continued to charge me for over a year. Comments like yours is what the AT&T Customer service reps told me but I finally got my full refund after I reported my case to BBB and FCC as stated in my original post. The office of the president at AT&T finally admitted the error and paid me back. Yes, I made a mistake of not checking my bank account each month to make sure AT&T was doing their job right, but does that really excuse AT&T of charging me for a service that was never provided-for the billing mistake that was made on their part? My intention of posting is help frustrated customers like me because I know how hopeless it feels to get zero help through AT&T customer service over the phone.
