Rapinet broadband amatures

We have been with Rapinet for internet access for the last year approx. We have endless problem. We have to phone daily because they have a IP problem on there network. If you call, them is it nothing out of the usual to hold on for 30 min IF they answer. We signed a 2 year contract for uncapped internet at speeds of 10mbs. But on the best days we get between 3 and 5 mbs. It is pathetic. We would like to stop this contract immediately and seek other connections more staple.
