Voluntary deletion after sending a DV usually means the debt collector is no longer involved with the collection, either because the creditor has terminated their account, the debt collector has withdrawn, or the debt has been sold to another.
With the debt remaining unpaid, someone will usually continue to pursue it. It is certainly possible, and even likely, that a new collection will pop up.
The OC may be pending sale of the debt, and thus a reason for termination. Or they may just want to secure a different debt collector.
