MTN-NO DATA OR SMS FOR MONTHS ON END

For the past couple of months I have not been receiving my data and sms's that i'm due at the end of every month... Being busy with work and occupied with life in general I thought that somewhere along the line I had missed the boat and for some reason just seemed to be finishing my data at a rapid pace and just started just buying bundles and sms's myself-Months later I discovered that MTN were only loading my free minutes and NO data and NO sms'. When I spoke to a service consultant about a month ago she basically stated sorry- Nothing we can do and you will be credited in the next month but you will lose all other months that we did not credit you. She felt no empathy and couldn't care less-Waited for 7 November, Still nothing-Today is the 9th Nov, I have called customer care and they have advised that it is under investigation and I should receive something back- Just a waiting game... The service has been really terrible though. I have been with MTN for over 15 years and this is truly sad, Hope that I get more than 1 months credit for the inconvenience caused and the financial implication on my side...
