RCS needs to stop dragging their feet and send me my settlement and closure letter!!!!

I paid off my Pick n Pay store card just short of 2months ago. I called numerous times for a settlement letter but havent received anything to this day even though i was promised to receive it within 2days each time i called. Over and above that, the consultant i called said that i would receive a closure letter after 30days of closing the account, still havent received that. When they want your business they are very quick to call but when business is taken away from them then they couldnt be bothered.
