Homecloud Bad service and line speed

I have Homecloud as my ISP for close to 2 years , not because they are so good but because they lie, threaten and in general does not help you. since I had my line which was promised to be 10mbs plus I have never had any speed higher than 2 - 3 mbs on any time I needed it. I have spent hours on the phone and emails with Jean Castel-Smith and Verster Erasmus to cancel the service and stop my contract as I am not getting what I am paying for. I was promised that it would be but it was never done. after that when I phoned I was always put through to cancelations where I was told that I will be fined and if I did not pay I would be backlisted. I just wish there was some way I can get rid of the contract so that I can find a new ISP
