MTN-DO NOT UPGRADE WITH THE SERVICE PROVIDER

I am so frustrated with the service that I am getting from Sibusiso Masina and team leader Thato Mosinye on behalf of MTN. This has been coming on from September where the agent put me on the wrong package. Back and forth calls and emails yet the matter still does not seem to be resolved. I keep on getting incorrect statements reflecting incorrect amounts and premiums. My line gets suspended monthly because their accounts are wrong yet I pay every month. According to call recordings and contract agreed apon I should be paying R399 pm. I was told that the matter was sorted yet IT HAS NOT BEEN Fixed. I've been dealing with consumer protection but it seems mtn just doesn't care about their clients as they still just ignore my complaint.
