Whose client am I anyway?

<p>I was utterly disappointed with the service and run around i got from the mtn cancellations department. When I called the call centre to cancel my contract, I was told that the month to month contract that I had originally agreed to had been loaded as a 24 month contract by an Mtn service provider and that Mtn, who are receiving my monthly debit orders, cannot reverse this transaction or cancel my contract. I was then refered to the third party service provider who said that they couldn't help me because I was transfered from Mtn directly and that i should call them directly. I had a further 30 minute wait before cutting the call due to "high call volumes". </p> <p>Whose customer am I anyway and why is Mtn shunning their responsibility?</p>
