Channels timing out.

I am ready to leave Cox.  The cost is prohibitive even with the bundle.  Why am I paying so much money for cable TV if cox continues to time me out.  I am handicapped and mostly bed ridden.  Cox has the gall to time out the channels if you don't constantly change a channel they take you to the God awful cox channel with music that brings me out of a dead sleep.  Sleeping for me involves sound that I want to sleep too.  How do I get out of the contracted bundle I signed up for trying to save money.  I now want something else because this is my last straw!  Too much money and then the audacity to tell me how long I can watch a channel without constantly checking in.    AGAIN HOW THE *** DO I CHANGE COMPANIES WITHOUT BEING CHARGED  A FEE FOR LEAVING?
