Discovery Card Cancellation Impossible

I have been trying to cancel my card since 26th of May 2020.Received a email that I must complete a account closure form and a amount of money will be refunded to me. After I submitted the completed form, they have not responded back. Guess what, I get charged more bank charges. I send another email to them on the 21st of June, receiving a automated response, yet no response after that. It will be a month after I originally requested them to cancel my card, they still send a statement with charges, still send a email that my account will move to Discovery Bank and yet refuses to respond and cancel my card.
