Mtn Bad Service

I have been trying to resolve a query about a data bundle from January. I received a sms treatening me to pay an X amount or else my services would be suspended. I did not agree with the amount. I paid part of the amount as I knew R149 was a databundle I have purchased in December and settled it. I called more than 5 times about the R99 query and every time these timeconsuming calls just waist my time. I get empty promisses about them lodging a dispute and that I would get feedback. I was even promissed a call back on Friday but no response at all. I even told the gentleman at MTN that I receive another sms stating only I should pay the amount and treatning suspention but not feedback re my query. I know while a dispute is lodged they cannot cut my service before I get feedback and just like I feared, this morning my services are suspended. I tried calling them several times this morning NOBODY answers just a prerecorded voice telling me to pay reconnection fees. This is just plain bad service. I did not get any feedback from MTN via call or email yet they have the nerve to suspend my services before resolving my problem that is dragging a month now.
