10 years on an account sounds very long. In Missouri I think that is on a Judgment, not an account or a contract. I think you need to check on that. you may be outside of the Statute of Limitations.

The last activity on the account was 2010. It was a checking account. I read in Missouri that it is five years for credit accounts, and ten for others, so yeah, I'm close, but not there yet.
