This bank re-opens old accounts and then charges services fees on them. Free money

This bank re-opened a credit card which I closed in 2014 and now is charging me service fees for an account that is supposed to closed, absolutely impossible to get hold of anybody that knows anything, on a call for an hour, Facebook Messenger, nothing works. Basically identify theft within the bank. One person said they knew about the issue so it seems they'd rather keep quiet and hope you don't find out than contact affected customers
