I was charged after my contract expired

I signed up for a 24 months contract and they still debited my account months after my contract expired. They claim my contract said after 24 months it will be a month to month basis but I wasn't informed when they rushed me into signing up with them. Its day light ******* because now that I'm a member they don't care anymore. They are telling me of how I didn't read my contract which they didn't even bother giving me before I signed up. All they care about is signing us in and only explain what suits them.
