Bad Service

I received numerous of sms of promotions on data than will be received by MTN based on the data usage. What surprised me is that no one knows or care to find out. One of the call center agents offered to get info and would call back but didn't bother to do so. I'm really fed up of MTN, the data is expensive and the service sucks for the amount of money hat we spend. I've converted my whole family to MTN but we are currently in the process of porting to a more reliable network. I normally advised everyone that I got in contact with to change to MTN but will never. waist of time and money indeed. ive been with MTN for over than 15 years but will have to go.
