My ex roommate and I agreed on a lease agreement with discounted rent because of bad carpeting. We stayed there for 3 years and have gone our separate paths for the last 2 and a half years. I just got a letter in the mail from the lease management company where we rented. The letter says that we owe a little over two thousand dollars for having a bad carpet when we left and if we dont pay in 10 days they will take further steps. What should we do?
