Cancellation not processed to bill me

I cannot recall ever being happy with MTN's service. This is not the first time I am complaining and quite frankly they don't seem to be moved by any complaints from numerous clients might I add, as these seem to just be rolling in by the minute...<br> <br> My contract matured on 10/04/2015. I called prior to this date and was asked to call on the date of expiry for this to be processed, now that part confuses me already as we live in a world rich in technology and this can be captured, sent through to the relevant department to be actioned on the DATE OF EXPIRY, however being the humble person I am, I did as I was asked. Called MTN the 9th and spoke to Ability who advised cancellation was sent through, Mthela on the 10th who advised cancellation was sent through-*** and today Tebogo who advised Cancellation is having a maintenance prob-***.<br> <br> In the meantime airtime has been loaded again after cancellation, and who will be liable to pay an instalment? I have paid in advance and want my money reimbursed, I refuse to pay after I have cancelled, so please refund me IMMEDIATELY!!!<br> <br> Cancellations, pls do your job and cancel so you can refund me, NOW!<br> <br> I'm awaiting a call!
