These people keep calling about a debt that was paid years ago. Even though it's no longer on my credit report, someone seems to have got ahold of it and is causing me a great deal of grief attempting to collect on it.
I flatly told the caller, each time, that the debt has exceeded the statute of limitations for collection and that it has been paid. Then I hang up. They call back and rudely request "paperwork proving the debt is paid." I've reported them to the FCC. I don't know it'll do any good.
