3G DATA JUST GOING MISSING - MTN *****ING MY DATA

I have been with MTN for years and will for sure know if something is wrong with my Account or 3G DATA. I do keep a strong eye on my expenses. AS LIVE IS EXPENSIVE CANT AFFORT PEOPLE TO ALSO ***** from you. <br> <br> In short: I bought 5 G last month on a special where if you buy 1g you get 1 g for free. Every time I bought this special I got cut off after using the first 1g. so the free 1g never got to me to use. Every time I phoned the call centre just to be told PLEASE BY MORE DATA. After the 5G I really got fed up and was put through to the billing dept. who informed me that I still have 5.5g left and cant understand why I don't have data. So the query was escalated to the FBI dept whom you can t contact directly-----it was suppose to be resolved within 48 ours. ...I am still waiting. the ref is #***. Please resolve this issue or else I will stop my contract with immediate effect!! this is theft!!! How must I do business without data ? Plus your call centre is constantly receiving high volumes of call --- wonder why. your call centre system is also so SLOW that the person in the call centre cant do his job?? One system at MTN sis NO Data and the other one says YES DATA
