I got a letter from them a couple of days ago, followed by a phone call the very next day. Mind you, the debt in question was paid off two years ago, and I have a letter from the debt holder that proves it. When I told them I had this proof, and that I would be filing harassment charges against them and notifying my lawyer about their attempt to collect on a debt that had been paid off, they couldn't get off the phone fast enough. I called them back - the number on the letter went to a voice mail box that didn't identify who it even belonged to. I called the same number again, and it went to yet a different voice mail box. I left messages on both saying that I wanted their fax number so I could fax them the letter showing the debt was paid. Amazingly they have never called back. This kind of makes me think they are scam artists and are just hoping people will pay up to protect their credit. Thank God I have saved that letter!
