Portfolio recovery horror sotrys

I had never heard of this company before and they called me today. Connection was bad or something and they asked for me, I said "this is him",  I asked who was calling and they said it was portfolio recovery.  The connection went bad and call disconnected.

     i just looked up this company and have found horrible things that have me worried. I have good credit, make payments on time. i ran my free annual credit report and there are no collections. Portfolio recovery only shows up on Transunion under
account review inquery, two times in 2010 and just last Dec.

     I moved to another state last June, both states show SoL to be 4 and 6 years. I know I dont have any delinquent accounts in the last 7+ years.

     Should I just do nothing and wait to be contacted again? if so, what would i tell them on the phone? If I ask them to send me something via mail, should i have to give my new address or dont even give them that if they dont have it?

     If they call back, should I ask for all information they have on the debt so i can have info to send them a VoD letter?

     Basically, I know its very early in the game but i know who they are and they asked for me so it cant be good and I have to assume they want to pay a debt that either isnt mine or way out of SoL.

I just dont want to trip up and cost me money I dont have.
