Unable to close account, despite multiple tries.

I'm finding it impossible to close my discovery credit card account. Every time I phone they either cut me off, or put me thru to the department responsible for closing the account and then just put me on hold indefinaetly... today Monday 24 August 2020 @ 3:23 pm I'm holding and are on 26 minutes + without answer. These guys charge me every month for the discovery credit card that I specifically said I din't want (when they moved over from FNB) and I have tried multiple times to try close the legacy account. I'd hate to get a negitive credit rating for unpaid bank chages on a card I don't even have, which they bill me for evey month, don't want and can't despite my best efforts, I can't close. Discovery if you are reading this, I have discovery life and health... if you don't fix disgustingly bad service issue, then I'll consider closing those too....
