Gold Credit Card Dispute

I have repeatedly requested that my Standard Bank Gold credit card account be closed, both in person and over the phone, yet it remains open. Since October 2023, the account has been in credit (R600), but Standard Bank has continued to charge me monthly bank and card fees, despite my belief that the account was closed. Since October 2024, I have been contacted by Standard Bank for outstanding fees, and each time I pay the amount and request the account be closed again. As a pensioner, I feel it is unfair to continue paying fees for an account that should have been closed, and I believe Standard Bank should reimburse the funds taken since October 2023 and finally close the account as requested. I closed my savings account as well, but if they did not close the credit card Standard Bank might not have closed the savings account. Please rectify this issue as soon as possible.
