I paid $2800 to offerup for a '79 Chevy coachman cadet apparently being sold by a military woman through an OfferUp invoice email. OfferUp had apparently takin the full $2800 yet hasn't replied with anything about a delivery or anything. The seller has not even replied, it has been 2 days now for any communication. Now I have all the emails to both OfferUp and the woman, all the receipts, and cards. So I have all the information. I had even warned that I would call the bad she claims to be on. User's recommendation: Don't have any advice I just feel completely used and dumb.
