i have an outstanding balance

Who is your debt to?
Are you dealing with the original creditor, or a collection agency?
Do you have any proof? Bank records (like a paid check)? A paid in full letter?

Welcome to the Community :D This is not a specific collection company, but a debt and credit forum relating to debt. If you can tell us what company you are trying to reach, we can direct you in their direction. Keep us posted!..Karen
