Oh it should definitely be a zero balance if the account was sold off to LVNV (WTG on getting a settlement out of those A-holes!! Good for you!)
Have you ever tried disputing it? If so how long ago, how (mail, online, phone), and what was your dispute reason?
If not....then do so. Not sure if you can get them to fix the lates (just like with the other you can dispute the lates too though) but you should at the very least be able to get that at a zero balance....
If it still comes back verified you need to send them a
debt verification letter (NOT a validation letter - there is a difference).
*Be sure to always send disputes CM (not RR) and then any correspondence to OCs/CAs CMRR.
