*****ing Data with no Network Coverage

I had 40MB left of my monthly Data. I wanted to download a 135MB game. So I bought a Rush Hour 100MB for R10 + R1.50 for an additional 10MB to make sure I dont use most of my monthly data. I started the download......then when the download got to 53MB, the network froze, which is no suprise as they have the worst downloading speeds I have ever seen (H+ downloading at 100kb/s). Then when I looked at my data again, MTN stole alll total of 150MB from my tablet....every little bit of internet I had left after jus 53MB. I suggest you go to any other network as MTN went from the best to the worst in the last 2 years. Their spees are the slowest, rates are insane adn service utter ****. My Cell C Blackberry Bundle downloads 4 times faster on 3G that their H+. Cant wait to cancle my Tablet plan this month with them and wipe them out of my life for good.
