If your original creditor was removed from your credit report can you dispute the collection agencies still showing the debt and have them removed also?

No, the original crditor was removed because the account was sold to a third party collector. The entry will remain on the report for the required 7 years from the DLA.

You can dispute the collection agency entries as well. Often times if you have paid the debt, the collection agency will no longer keep records, thus be unable to prove the debt when you dispute it. They more than likely won't even respond, as they got their money and don't care anymore.
