Does anyone know how far back a creditor can go back to collect on a debt? As I've stated before on here, I am being sued for a credit card debt, a credit card that I never applied for, received, had possession of or used. But they are saying the last activity was over four years ago. I was under the understanding that the statute of limitaions on a credit card debt was four years. They are saying the last activity on the card was over four years ago.
