Redline Recovery Service

I just received a call from Christy and she said an old Sears debt of my husbands had been turned over to her and it was a "prelegal account". I asked her what that meant and she said they were just before legal action and these folks meant business, they could and would place a lien on my property, garnish my wages, etc. I told her I had no money to pay anything and she told me that she represented LV Funding. I told her I had gotten other calls and had sent validation letter with no response. She said the validation was my credit report to check it and I would see the validation. I told her again I had no money and she said she would email LV Funding and asked it they would accept a settlement (in monthly installments). Someone please advise me...I don't further action from these people!
