Impossible to close account

Closing the bank account from abroad OR moving it before to a non-resident account is an impossible task. We have handed in every paper they have asked us for, but they have either lost them or not given us all the information. So it has been over 6 months that we have tried to close the account, without any luck. And of course, we are paying the fees every single month of not being able to close the account. It is infuriating. As an expat having to keep a bank account open after departure, this is NOT the bank that you want to choose.
