False advertising

Hi people Ive had my adsl line since the middle of August and everything was fine I got a 2mb line and the speed was not great but fair. I then started getting bad speeds and then when I called the consultant said that I was throttled due to the fair usage policy. I then told the consultant that I was not explained about this policy and niether did I ever get speeds higher than 1.6mbs. So now i want to cancel my contract but i must pay a penalty, how can I pay when telkom is not providing me the speeds that they say they will give me. I get a download speed of 200kbs and when I get throttled I then get 30kbs so that is more than half the speed. They can also not tell you at what amount of data you will be throttled. <br> <br> I even went as far as upgrading to a 4mb line but still not helping. Can someone please help me.
