Charging for phone not delivered

I upgraded my contract on the 26 June. They started charging my almost immediately. More than a month later I am still waiting for the phone to be delivered. It is impossible to get hold of anyone at MTN. The contracted company that did the deal gave me the name of Roger Adams. So I guessed his email address. He phoned me today to say that he will look into the problem and get back to me. Needless to say he didn't get back to me. So I tried phoning him. He doesn't answer his phone and you can't leave any voicemail. And this is a telecommunications company. Obviously MTN is so *****ed up it can't be fixed. If you are considering being an MTN customer don't. Nobody cares and nobody can help you. As for Roger Adams, he is not a man of his word.
