Cancelling an account with just the Invoice BAN
All I want to do is cancel an account that has an Invoice BAN number and 1 phone number on the account. This only bills long distance. Originally, there were about 9 numbers on this account that we ported over somewhere else. For some reason, this number was left behind and kept accruing costs. I've been on the phone just this morning for 3 hours trying to resolve this. No one I've spoken to is able to find this account using the BAN or the phone number and I've been transferred approx. 11 times to other ATT reps who also have no idea what to do with the BAN number.
All I want to do is cancel the account and open a billing dispute for the charges we've accrued. We had never re-signed a contract with ATT and can't figure out why we're still getting MRC charges here.
