MTN ke masepa

I recently upgraded my phone telephonically and up to this day I haven't received my device. When I call MTN they tell me that my upgrade was done via CCI and that I should contact them directly. However MTN is debiting my account regardless of the fact that I don't have the phone. I have been waiting for a month now for the phone and when I tell them that I want to cancel the contract since they are not delivering the phone they tell me it will take 21 days to get the contract canceled. In the meantime I'm paying for a phone that I don't have. I'm so disappointed at MTN and I will be taking legal action.
