Yet another Debt Collection Scam. Never pay the debt collector if you do owe anything. Always contact the person/company you know and pay them. When your debt is paid off, they'll contact the debt collector they hired/turned your bills over to, and tell them the debt is paid. Oftentimes, debt collection agencies pick up third party "debt," and try to get people to pay what's already been paid. This is why you never pay the collector. They all try to scam you.
