So I have an account originally opened in 1999-2000. It has not showed up on my credit report for close to a year now. A collection agency has recently contacted me, offering me a settlement, the account total debt is about 1,600 dollars - they offered a settlement of 1100.00. I know that if a payment is made on the account, it restarts the statute of limitations. However, because it no longer shows up on my credit report, I have no idea when the last payment on the account was made. It very well could have been over 7 years ago, but I'm not sure if I made a payment to one of their creditors in the mean time. I honestly can't remember the last time a payment was made. Is there a place I can go to see accounts that have dropped from my credit history and when last payments were made? Should I simply dispute the bill and see what happens? If it IS past the statute of limitations, how do I go about proving this in court?
