TERRIBLE CUSTOMER SERVICE!!

I signed up for a contract with MTN The Glen on Friday morning the 4th August. I was assisted by Boikanyo Makua who was efficient. I phoned MTN The Glen on Friday afternoon as I did not have internet from my contract which I had just signed up for. The phone rang at least 8 times before a woman answered and said it is probably the SIM card (Ricca). She said she will pass on the message for Boikanyo to phone me back. He did not call me back. I tried calling at least 8 times again before someone answered. This time it was a male who was not very friendly. He told me their system was down and that is why I did not have internet yet. It is now Sunday morning 09:30. I still do not have internet. I have my phone on redial and I am attempting to get hold of them at the MTN Branch, The Glen. This is now 14 times I am calling and the phone is not answered!!!! This is totally unacceptable customer service.
