Dispute, validate, negotiate and pay origianl creditors only. File FTC complaints

The company I told you about that didn't want to scare off after I requested validation. Well, I filed a complaint with the attorney general consumer division in my state and within two weeks every account was wiped clean and the creditor (who was always nasty!) sent me copies of the request with a polite letter signed "Sincerely". Thought you'd get a laugh!
There was only one creditor who actually had files after selling the account (scary), but, they admitted they have no signed contract by me and they are looking for it. If they have nothing signed by me can I still pursue deletion?
