FNB lack of contact and resolution to a simple problem

This seems to be the only platform that I can get hold of FNB, I have still not been assisted by the revolving facility department, I get the run around from customer support explaining *** has been assigned to a Service Resolution Consultant in Retail Service Recovery. I have spoken to a consultant and was assured that the revolving facility department would get my query and sort it out. Honestly how hard can it be to settle and close an account that has been fully paid up and I am being restricted from doing it on my online banking, which should be available to me? If any interest or cost is added to this account while I have been waiting for 2 weeks for it to be resolved I will flat-out refuse to pay it.
