CACH LLC lawsuit

I was recently sued by CACH, LLC, i had heard nothing from the company prior to suit. I have read alot of bad stuff about this company and was given the advice to request debt validation. I sent them a certified letter in febuary asking for validation of the debt amount and the origional signed contract after their employee told me over the phone when i requested it that they could not provide it. We went to court and i pled not guilty, the plaintiff asked for interogitories, after i awnsered their questions, I asked about them denying my the information I was entitled to through the fair credit collection act. Today in the mail i received a Affidavit of claim and certification of debt from the origional creditor. in it they state that the origional contract had been destoryed and that the affidavit is to be treated as the origional contract for all purposes. How can they make an "origional contract" from something that i did not sign. they also included 6 statements from the origional creditor with my address highlighted. what do i need to do next?
