PC Network is Wrong Point...

So After being with PC Network wireless internet service provider for over a year, I just recently ran into some big problems, ....obviously I should have known NOT to trust a NEW company that is mismanaged! I applied for a uncapped wireless internet bundle at R1598 per month and everything went well until a month ago (obviously when the company have reached their profit threshold and was on the way down) so now my internet speed was capped to a 4mb line and when I called and spoke to Vince he was barely able to speak but what I could understand was that if I did not use less data they would cut my internet permanently. sooo I asked to speak to the owner whom obviously was out of the country lol. PLEASE tell me if paying almost R1.6k suffices for a company withdrawing your internet?
