No feedback after 2 weeks

On 13 January, I called FNB to close my Premier Cheque Account and Credit Card. When I log into the app, my credit card account no longer shows, however the cheque account is still open, and now I see that I have been charged with bank fees on 21 January. It's been almost 2 weeks and my premier cheque account is still open. I want written feedback to confirm if my credit card account is now closed, and I also want to know when will the premier cheque account be closed. I also want to know what happens with the bank charges? You cannot expect me to pay because you take almost 2 weeks to close an account. I have received absolutely no feedback from you in this time. Pathetic service. Respond to me by email and do not attempt to call me.
