It sounds to me like Action went out of business. This would be a great opportunity to DV the CRAs. If they truly investigate, there will be no response from Action and the item will drop from your report.
But, Remit may start reporting to the CRAs so you may still need to DV and PFD them if they do. (if the debt is still withing SOL).
If you're really looking to settle this account, you could DV the OC, if they're reporting on your CR. If they still own the debt, they may accept a settlement and change your status to Paid as Agreed rather than as a Collection.
