Assetcare, Inc. review: fraudulent collection agency 1

I received a collection notice from this company for $235.00. On this letter, it gives no mention of who Assetcare is trying to collect funds for. I know I have no outstanding bills, so I called them. I gave them the account number they have on the notice and they asked my name, which I provided. Next of course, wanted the last four of my social which I declined. I asked who the company was claiming I owed them money and they said they could not tell me without my social. Told them I would be filing a complaint with the FTC and they hung up. Be very careful and beware if you get any mail from them.
