Being sued for not paying a ridiculous bill

I wished I would have read these reviews before I signed up with them. They are attempting to sue me because I won't pay them $666 or so. When they called, I was asleep and I am disabled so I was under the influence of some medications that make everything blurry. I thought I was just accepting the contract I had just extending it a few months or up to a year or so, I don't know, but now they are suing me and I have no earned income and can't pay my bills as it is and yet they keep calling trying to scare me with a lawsuit. Stay away from these people. Please!
