FNB Refusal to close credit card account twice & Ignoring customer requests and complaints

This is my second complaint on Hello Peter regarding First National Bank Credit card division. On 3 Nov 18 I settled my credit card, filled in a form at Waterfall branch to close the credit card. Thereafter I heard nothing for one month. As monthly fees are deducted every month from credit card funds I again was charged in Dec 18. I called the customer care and was advised that they did not receive anything. So application was redone early Dec 18. Again nothing was done and I received statement that fees will be charged again early Jan 19. I wrote emails twice to ********** that was ignored and unanswered till today. I settled outstanding account again and complained on Hello Peter later in Dec 18. FNB came back to me immediately via sms ref number and cellphone and apologized but stated again they cannot see request to close credit card and will escalate this to the credit card division. I again send email to ********** but not even a reference number. This is the reference number for first complaint Ref number ********** NF. Now again in Feb 19 I am charged for fees due to FNB inability to honour customers request and complaints. Absolute refusal to carry out my request.
