<human>: I'll try to keep it as short as possible...

Today, My Fiance got a letter in the mail saying they are closing her credit card account. She has had it for awhile, using to build up her credit score. Has never missed a payment and pays more than the minimum each month.
 
After hours on the phone we figured out it was closed because a few months ago she had lost the card, got a new one (had to get a whole new account or something) and when they transferred everything over to this new account they somehow re activated a auto payment she had turned off April of this year. For some reason BofA was charging back the auto payment, or however that works, and because that happened more than 1 month in a row they shut the card off. Mind you she was still making payments, last but it was only because the auto payment wasn't going through, one that she hadn't authorized. The credit card people said there is nothing they can do at all because the account is already closed. She is super upset that this will be on her credit report because she didn't really do anything wrong. 
She was never notified of the auto payments not going through, first contact was from them saying the account has been closed.

What can we do to attempt to fix the situation? Anyone we can contact?

Can you summarize the given text in a few sentences?
<bot>: Fiance's credit card account was closed because of dishonored auto payments(which she cancelled in April of this year), while still making more than minimum payments each month.
