Poor service from Vodacom

I have been struggling now for 2 days to get help from Vodacom. My account is suddenly in arrears and I don't understand whys, and no one can tell me why, they stop my service without a warning. I did make a payment and send all the information through to them to a few different email addresses, called more then a few times, and every time they give me another story or refuse to help me. As soon as this contract end I will not be staying with them. I want a place that gives you service and help you there and then, not having to send you from one place to the other. The people in customer service is so pathetic, they don't know how to help you or even want to help you.
