BILLING QUERY GOING ON FIVE MONTHS!!!!!

I have been liaising with MTN since the end of October 2014 regarding a discrepancy on my bill. They quoted my a subscription in writing and every month, it is R 500.00 more than quoted rate. Every month, I have to contact them to resolve. They pass a credit and arrange a refund. I have been dealing with Richard Gardner and Jay Govender from the Office of Chief Customer Experience Office. They have both assured me on more than 1 occasion that all has been rectified and error will not occur again. I have received my latest statement and it is incorrect again!!! <br> Surely this is a waste of manpower and time to have to \fix"it every month as opposed to implementing the necessary to prevent future issues??<br> I am disgusted at the incompetence and lies of MTN.<br> Please provide me with the Operations Director as well as the Chief Operating Officer's contact details.<br> Another thing"
