NEVER JOIN MWEB

I decided to switch over to Mweb at the beginning of this month thinking I would saving some money. I took a 4mbs uncapped option for my home and a 8mbs uncapped for my business because thats the highest I can go with the adsl lines. But the speed has been **********. I Tried to cancel after 2 days saying I would pay for the month but they say I have to pay for 3 months. and they have also capped me at 93 gigs when I was told repeatedly I would only get capped at 110g. The network is unstable as even playing a mobile game that requires wifi cuts out continuously. I should have just stayed with telkom. Instead I'm stuck with something that is a pain to use. I told them before I signed up that I stream a lot and they said this was not going to be a problem as even if I did get throttled it would only be to a 2mbs connection. This is not the case as I'm getting .40mbps on speedtest. How do get out of this contract without getting sued?
