TERRIBLE SERVICE!!!!!!!!

MTN YORK STREET, GEORGE Terrible service! I did a simswap on 30 August for my contract data simcard. On Saturday the simcard was not working. I went back on 3 September my whole lunch hour down the drain to be advised that it would be done tomorrow and the simcard will work the consultant, Olga took my number and would call me. On 5 September I still did not have any info and the simcard was not working. I went to the store again. Another lunch hour down the drain. To find out that she did not do anything. She requested that I call customer service to ask what is wrong. I called while in the store. The consultant on the phone said that simswap was not done and that I must go back to the store to redo it. I gave this info to Olga. Sat there again and waited. To be advised again that it would be done the next day. When I told her but that's what you said on Tuesday her response was "ons is besig" This is terrible service! I pay for the simswap, pay my account but still cannot use my own sim with the data I pay for every month. Poor customer service. I NEED THIS SORTED ASAP.
