SketchyDebtCollectionsFilter: Someone calling and demanding payment on a credit card that was paid off and cancelled in 2002. Fraud? Error? What can be done? Asking for a friend who wanted to remain anonymous. Their words follow: Someone left a message for me today about an "overdue Mastercard" -- a "Very Serious Matter" that I needed to get back to him about immediately. I called the 800 number he left and spoke to him, at which point he brought up a Visa account I'd paid off and closed in 2002 to the best of my knowledge. I had a bad run in with credit card debt and international life and not getting mail back in the first two years of this century, but in 2002 I paid off and closed nearly all my accounts.
