Cox Communications I told the sales rep when I signed up for service NO CONTRACT Phoenix Arizona

In February of this year I contacted Cox Communications for Internet and Cable services. At that time I adamantly told the sales rep that I was only interested in services requiring no term contract. The sales rep assured me there would be no contract needed. now 5 months later I find out Im on a contract. Cox's way of rationalizing it is that on the first bill it supposedly mentioned the contract. I didnt take the time to peruse the entire bill.  I looked only at the amount due and paid it. This is usery in finest sense of the word.  I'm sure that I'm not the only person thats encountered this, and a class action lawsuit should definately be considered. Cox refuses to help me and offers no relief.
