<prompt> Human: Here is the question. Is there anything we can do to fight a bill that shouldnt be there or should we just pay it? Here is the context: In 2013, my husband moved to his first apartment and opened an account with ATT u-verse. In 2014, he moved to another apartment and asked ATT to transfer the account. Unknown to him, they opened a new one and left the first one open. In 2015, he and I got married and he transfered account 2 to the new apartment. A few months later we closed account 2.In February 2016, we went to close his bank account that was feeding the ATT automatic payments and found a weird ATT bill. We called and found that he had continued to be billed for both accounts. It ended up being around 1k. We couldnt prove that he had asked for either account to be closed so we bit the bullet and paid it and closed both accounts. We asked for proof that it wouldnt come up again and I remember being satisfied dont remember what the proof was and they refunded us a small amount for account 2 we have the check stub. Today he got a call from a debt collector for 200. He was confused so called ATT and after the ring around it they said it was account 1 and it had been closed, but then a payment went though which reopened the account. This was probably our attempt to pay out the account. We then were billed for another two months before they turned off the service because of lack of payment. We never got a bill. Obviously he was at fault for not noticing the odd bills, but hes learned and we watch for that now. Is there anything we can do about this new bill? We have proof of the refund for account 2, but cant find proof for account 1. They wouldnt even tell us who we could call to complain about this to.  <response>: If ATT does nothing, file a complaint through They helped me with a 8 month issue with a debt collector. Ended up getting 8 months worth of negative notes being taken off of my credit report and all fees reversed.
