Outstanding and in arrears for payment that i did

Collections department at Ackermans is giving the run arounds regarding the payment that I made during the covid 19 pandemic break as we went able to go to the store and make payments. They send the banking details that we should use to make payments of I did, now I am in arrears because they say my payment doesn't match the my account no: as they asked we use the card no: so I'm tired I've sending proof of payments and bank statement still not resolved.

please let them do what is necessary and send my money back as I don't want anything to do with them. All I want is to close this card as I'm tired of them now there are more retail shops that I can spend my money at
