Capitec preventing me from exercising my right to close accounts

I have been trying to close my credit card and savings account at Capitec. I went to a branch and have settled the credit card balance in full and attempted to close the account. Capitec however, is refusing to close my accounts as I apparently have to wait 45 days. I was never informed of this and the agreements signed never indicated this fact. I have contacted the call centre on numerous times but every time I’m told that they will escalate the matter and provide me with feedback. Nobody at Capitec even bothers to give me any feedback as they are effectively ******ing fees out of me by preventing me from exercising my right to settle and close the accounts. It seems like I’m stuck with Capitec for life as they plainly refuse to close any accounts and lose customers.
