BAD SERVICE re: Cancellations

Yesterday I requested for a contract cancellation fee and was advised via email that it will be R6279.74.<br> No detailed breakdown was provided of what this cancellation charge consists of. This is unprofessional, doesn't MTN have company letterheads and proper cancellation documents.<br> <br> Today I called to find what makes up this charge and was advised that its the handset fee plus my subscription of R429. Once again my subscription is approximately R383 and not R429, where in the world do the MTN customer service consultants come up with these values??? I was then told to contact my contract administrator/credit controller by the name Mbali on *** to resolve this matter as the call centre is not authorized to calculate cancellation charges, as usual these people never answer their phones and I do not know what I have to do now...!!!<br> <br> APPALLING SERVICE!!!<br> <br> I need a properly detailed out cancellation fee for my contract.
