Extremely bad service moving

I called into he call centre from 8 to 10 and guess what not no one answered is the service that bad. I have been given options I don't need on all the numbers I have called. I have been dropped while being told their are waiting for the next available consultant what nonsense. I have had it with mtn first it was getting my contract wrong and now the service not that it has ever been better for me. I am appalled at the dispeakable services. And my data finishing in 3 days after buying 1 gig that is just a *******. Funny I buy the freaken data and I am told it expires how does my own money expire really?? MTN IS ROBBING ME POINT BLANK AND IGNORING ME, you have lost yourself a customer the service is truly disgusting at this point . If someone does not call me I will go to the customer complaints department and lodge a complaint because you don't know how to treat customers fairly and don't care about the customer
