take your money and never answer your call

We were in MTN Clearwater Mall on Saturday to change my daughters number as she is being stalked by a crazy person. MTN advised us that they did not need to do a sim swop but they would call me, her mother, with a new number on Monday/Tuesday as that department does not work on Saturdays. Monday and Tuesday passed and no phone call. The number is still the same, however we have paid for the change. Today, Wednesday, i phoned MTN customre care, they told me to phone another number. I phoned *** and they told me i have to phone the store. I tried phoning the store and phone number is disconnected. I phone Clearwater management and they give me a land line number. I phone the land line number and they tell me, no, they are unable to assist as it is the other store in Clearwater mall. they give me another mobile number as the one that MTN customer gave gave me changed a year ago. i try the new number and that also does not work. Justin Pillay whose telephone number reflects on the invoice has cancelled his number. So we have paid for a new number, but nobody at MTN anywhere is able to help us. MTN save money and close your customer care. It does not work.
