Ok..A few months back, I was contacted by a CA regarding a credit card I had years ago..It was before I was even married. It was re-aged..sent from CA to CA...I have a good credit score, and this thing never even showed up on my credit reports.
Anyway, when I got the call a few months ago, I told them I would need their address, because I needed to validate the debt. I said I wasn't refusing to pay, but I needed proof. They hung up on me. A few weeks after that I got another call. Once again I asked for their addy. This time they gave it to me.
