Closing of Discovery Bank Account

I'm trying to close my account with Discovery Bank after having my Discovery Card automatically transferred to the above mentioned useless ****.

So Tlotlo Chweneyagae from Discovery Bank Client (Non-)Support phoned me and sent an email to confirm my external banking details, because I have a small positive amount to be paid over.

Now, the email stated that on their records they have my external bank account number and if I want to change it I should respond. So, because the account number is correct as per their records, I didn't respond. Cause, I don't want to nominate a different external bank account.

I consequently received an email 5 days later to tell me because I haven't responded they have closed the case but my Discovery Bank Credit Card is still active.

CLOSE MY ACCOUNT!!!!

I'm now at that point where I'm going to cut all ties with Discovery.
