Sharp Practice by MTN

I did an upgrade with mtn in Feb 2003. In April they increased the price by R19. Now they have ****** 20 of my free minutes which I have paid for and after weeks of emails they now inform me that my 'free' minutes are capped at 50 mins per 2 months so they just take them away even though I have paid for them and it is up to me when I choose to use them Non of this was explained to me when I took out the contacts. I consider this to be sharp practice on the part of Mtn.
