Unacceptable customer care from FNB

Its been more than a montn since I have trying to settle my fnb revolving loan and since then I have been sent from one department to another. Last week I was at the Rooderport fnb branch to inform them that I am struggling to make a payment to the revolving account using another bank and was informed I cant make the payment because I do not have an fnb cheque account.

Now how is this possible? Why couldnt the other departments help me with the right account number where the payment must be made. This is very unproffessional and I shouldnt be sent up and down as the customer.

I urgently need assistance with this as I need to close down this account
