MTN DOESNT CARE ABOUT THE CUSTOMER-NO AFTERSERVICE

MTN has no after service what so ever!!!! After destroying our damaged/faulty airtime vouchers and telling us that we will be credited, nothing has progress to any credit for a year now!!! They have just one employee that deals with this and she is fed up with us because of all of our complaints. So she just doesn't do it!!! We have emailed and emailed the whole of MTN, BUT no response from them. All they say is this one lady MAPULE is the only one that can do it and well we are really shocked about this slack response from MTN. We buy weekly from them. But they dont care about the customer. THEY CARE ABOUT THE MONEY
