MTN *******

In January my Uncle bought my wife and I data as a gift 10gig each. Where at the end of the month MTN expired our data that was a gift, my wife and I had about 9gigs each remaining that was ****** from MTN. Further more the lady from MTN phoned me the next day to say the best MTN can do is to give back only 5gigs each that won't expire. Now end of Feb MTN has expired our data again. I had about 4.5gigs left and my wife 2gigs so how much data from clients have MTN put back in the system, just from us. 6gigs from my wife and 8.5gigs from my self so 14.5 gigs in total. I'm ****ed off and MTN is a bunch of ****** ******* *****ing from clients. My next step will be Carte Blanche do you hear me MTN? I will go viral with a stink you won't imagine.
