Mtn *****s from its customers

Every month I purchase extra data from mtn and evey month they ***** 300 - 500mb of my data. It supposedly expires. I am so tierd of mtn *****ing from me. Add up over an year period how much data we all cant use that mtn just *****s back and then sells it back to us. This is sure and simple *****! . Why is there an expiry date. To force the customer to buy more. Just like price fixing ****s. Its ******* to ***** and yet big companies can ***** from us all and we can't do anything. If you ***** from them, well then you go to jail. How is that just or fair? When are we going to stand together and do something about Mtn? Why do we allow them to ***** from us. Refuse to pay them and you get black listed. How do we, honest south Africans get justice without getting black listed? When I asked them why, they compared it to milk! If you dont use your milk it expires. How can they say that. Shouldn't it be my right to use up my data. Every single byte? Mtn really needs a good kick in the nuts! Or its time to get an CEO thats not an ******! If mtn charged peanuts for their services, ******s and ******s in the top brass would of been understandable!
