Non cancellation of my Credit Card

I am highly disgusted with the service received from the Discovery Credit Card Department. I instructed them to close my account as far back as January 2020 and nothing has been done to date. They still have the audacity to charge me monthly fees and a once off card fee and sending me SMS's to remind me to make payment. I am sure the delay in closing the account is a ploy from Discovery to generate more income.

This type of service is not expected from the esteemed company they claim to be.
