Utter Incompetence - Cannot Close My Credit Card!!!

Wish I could give this "bank" a negative rating. I have been trying to close my credit card account for months now! On the 15th of July 2020, I notified Discovery Card division that my credit card had been settled in full and requested that the account be closed. I included all my contact details and a certified copy of my ID with the request. No response. On the 24th of July 2020, I requested an update on the closure of the account as it still hadn't been done. No acknowledgment was received whatsoever. However, the account was removed from my FNB profile, so I assumed that it had been finalized and closed. (This is how I always accessed the account) However, on the 9th of September 2020, I received a Discovery bank statement for the first time in my life! The statement was for some unrecognized account. Apparently, R39.06 in interest was charged to the credit card account after I had settled it and after it had been removed from my FNB profile. This was then transferred to a new Migration account but was then reversed on the same day??? Since then fees and charges have been raised on this new migration account. A debit order was initiated against my FNB account without my consent for payment of this new migration account. FNB claims there's nothing that they can do and I have been unable to get any response from Discovery Bank.

I have no use for or access to a Discovery Bank account as I am living overseas and have no active Discovery Bank cards in my possession. The account was settled in full and closure was instructed numerous times. However, charges are being raised instead. This action by Discovery Bank is not acceptable and smacks of *****. All the fees and charges are to be reversed immediately as I requested that the account be closed on the 15th of July 2020 almost 2 and a half months ago, and I never consented to a new account! I am not going to keep paying for Discovery Bank's utter incompetence. REFUND THE DEBITS RAISED, REVERSE THE CHARGES AND CLOSE THE ACCOUNT!!!!
