DON'T OPEN AN ACCOUNT WITH FNB

I have been trying for over 1 month to cancel by FNB credit card. Firstly I tried a branch. They told me I had to contact FNB Card Division. I called the card division who say it has to be done in writing. Tried to email the cancellation. No response. Tried to cancel on line using internet banking. No such option under cards or any other page to close the account. Many options to add more people but they do not want clients to close their accounts so that they can continue to charge the monthly fee for as long as possible. Until last year I have had up to 5 different accounts running but then closed the all except the credit card account because of disgraceful service from FNB in all aspects of banking.
