Still no solution

As per my previous post http://hellopeter.com/mtn/complaints/paid-up-but-not-captured-*** I was called back the next morning to ask whether I have seen the response and I agreed I have seen it. I was then told that I still owe money on the account and that everything is not settled. I disagreed with that as the external attorneys told me that the amount I had to pay over to them includes the cancellation fee. And I asked the external attorneys more than once that they make sure that is all I need to pay. I had to wait more than a week for them to confirm that nothing else was added. I was told that the problem will be investigated and given a call back but 2 weeks down the line and I have not heard a word again from MTN.
