DMC and Sterns

I have been sent back and forth with the account I had with Sterns handed over to DMC. I settled the account and was sent the settlement letter however the Sterns account is still showing under my records as active and not under closed accounts. Sterns response was “ We cannot clear the account balance or remove the account from the database. This however does not affect the Bureau records as the responsibility to update the client’s credit record after settlement lies with the collection agency.” This has been going on for months now.
