No response. No need for business

I app**** for a new contract. Still no response. I called the call centre who said to call MTN direct who then sent me to new contracts who then said I should go to the store. I called Joy from the store who said they needed to do a credit increase application. ****een was supposed to call me, never happened. I am with Vodacom and spending over 1000/m. I wanted to move to another service provider, however MTN is saying no to my business. I tried calling the area manager Sandra who either ignores calls or refuses to contact clients. Disgusting services. If they like thus at the beginning of a contract, is it worth going to them??? Boza my ass
