If you have been sued, speak with an attorney immediately. You have a defense of rescission if you gave notice in the time required. I can only hope you did this in writing. Regardless, email an attorney on this site to discuss this matter and see if they can advise or represent you.
Now, given this is small claims, it does not make sense to pay an attorney for a full representation. You can still see if any would advise you under a limited representation. Good luck.
