DISCOVERY BANK DISGUSTING SERVICE!

For the past 3 years I have tried to assist my father in closing a credit card account with Discovery Bank he does not even know how he has it in the first place. Each year he has to pay in money and they say once money has been paid they will close the account. They do not close or and he has to pay in more money. It is costing him and he has never used it does not even know how to or have a card or anything for it yet he must pay. It is so disgusting how someone can be ****** like this. I have spoken to various people received reference numbers etc and each time I get promised it will be closed but never does.
