HughsNet could not resolve my technical. I had to cancel I did not know I was locked into a 2 year contract

I cancelled my HughsNet service after finally discovering that the technical problem I was experiencing could not be resolved. I did not realize until I cancelled that I was in a two year contract with Hughs. I have been charged over $400 in cancellation fees after working for weeks trying to resolve this problem so I could stay with Hughs. I am so angry .
