Can not close acount after a full month of jumping through hoops

In the first week of December 2017 My wife requested to close her discovery Card account. The forms were completed and send in and an outstanding amount was paid in and then send it for close within a week. A week later my wife phoned again to confirm why the account is not closed and the response was that a request was not processed to cancel the card protection. The request was done and we had to wait for the month end before the card protection can be closed. On 3 Jan 18 my wife phoned again to confirm that account is still open and why it is not closed yet. She was informed that the card protection has been cancelled know, however the next action to cancelled the card was not done. This would be done and the account would be closed within 48 hours. It is another week later and still the account is open, I had to pay in the monthly banking fees again to ensure that the account balance stays positive and today my wife was told that there is another form she has to complete and then the account will be closed. We have not received the form and the will once again have to phone and follow up on why we did not receive the form and what we can do to close the account. I will not pay in another cent into this account until it is close. We gave more than a month notice with no joy.
