I had a similar situation when an item popped up on my DW CR.
I disputed it knowing that they would verify- This gave me the ammo I needed to get my AG involved.
He said to me "if they report - that could be an over sight, when the verified that are definitely trying to collect." I have no idea if there is any legal backup to this.
This was the outcome-
They settled with me for the amount we actually owed, removed from the DW CR, deleted all accounts from AZ credit reports and could either get licensed or go to jail .
