Absolute impossible to get a simple issue resolved

Visited the MTN store in Bethlehem to change ownership of a contract. The first visit was on 23 October. It is now 8 November (16 days), 4 visits to the store, numerous phone calls to the store, MNN help centre (Useless!) and 3 written complaints to the MTN complaints centre later. No response from any of the above No help No feedback It seems as if what should be a simple administrative procedure is a mission impossible for MTN I have tried everything and seem to be in a dead end.
