Credit card

I'm frustrated by the service im getting from standard bank, I've settled the credit card in full stoped using it in 2017 and yet being charged purcshases fee, i was told to settle the account again because they can't close it without the fees being paid. I paid off the amount owed on the 15th of June and sent proof of payment and requested the account to be closed. Since then ive never received feedback and send a complaint to their internal department but no one is responding to my query. All i need us a confirmation that my payment was received and that the account is closed
