Unresponsive/BAD customer service

I have asked for my early cancellation fee for three weeks now and have had NO feedback from MTN. Everytime I call I get told that they will escalate the matter and I'm not allowed to contact the retention department myself. And yet won't hesitate to blacklist me if I refuse to pay...<br> <br> Perhaps if they actually provided their customers with proper service, they wouldn't need to have a RETENTION DEPARTMENT because nobody would want to cancel their contracts???<br> I'm highly irate as I have been a customer for over 10 years. Can't wait to take my business to a supplier who will actually welcome payments...
