I changed from open line to top up on a data line at Peppergrove Mall Grahamstown. The migration did not go through causing an overbill of akmost R2700. After 6 visits to the MTN store andno successni contacted Angelique. In her usual efficient dedicated and real interest to solve queries thar which was within her scope action was taken immediately. I wish the credit control department could be staffed with at least with people that half of Angeliques positive disposition and decorum to communicate and particularly 'keep you abreast of everything" and ability to handle one piece of paper once. Well done Angelique.
