Credit card and cheque account

Two weeks ago I went into FNB branch in Strand to close my credit card account, and also to change the payment date of all fees on my cheque account to the end of the month of every month. Today when I checked my account,I was shocked to find that my credit card has not been closed and now have been charged R16,50 monthly rewards fee. Why am I being charged when this account should be closed? On the 17th my cheque account has once again been debitted, eventhough I have requested the date to be changed to he end of the month. The money that I had in my account was to get me through the month not for cheque account fees that I would pay month end!!! It was a waste of time going in to the branch to make arrangements because none of it was honoured. I demand that my credit card immediately be closed and my cheque account reimbursed and debitted as per my arrangements.
