MTN Bungle

This month MTN at their own admittance had a technical error and billed their customer base early. They suspended my service and demanded a payment plan for an account which is not due yet. I paid on the day I normally do as per my "Payment Plan" and this morning service has again been suspended. MTN, I have had a contract with you since forever and as far back when the first phone was introduced in this country. Maybe they no longer need my/our business......not a happy Tuesday :(
