I received a letter from Portfolio Recovery Associates LLC today on XXXX XXXX XXXX about a debt they purchased in XXXX. I paid the amount owed back in XXXX to clear the debt. The other problem is that had I not paid the debt is that the statute of limitations ran out in XXXX. 
They state in the letter " Because of the age of your debt, we will not sue you for it and we will not report it to any credit reporting agency. '' If I receive another letter from them can I take them to court?
