Fortunately my recent purchases from VC have been mostly in good order.
Mostly, because I bought a Hermès Evelyne TPM from a trusted seller who is always quick in her replies.
The bag came without the paperwork, but the seller said she had the receipt somewhere but was moving house and all the admin was in boxes.
Received the bag; it was stunning, but I read the blind stamp and noticed that A: the bag was from a private sale -VP: vente privée- and B: it was from 2014 and not 2016 as the seller had stated.
Contacted VC: I could send the bag back for a second inspection and indeed: It was accepeted, as "the description was not accurate" and I received my money within 48 hours.
Contacted the seller, who was genuinly shocked, as she had bought the bag from a friend/reseller in 2016, with receipt from the reseller stating that the bag was new at the time of purchase. The seller had found the receipt afer all.
So my suggestion is: Send the bag back to VC for a second inspection, accompanied by all the paperwork and at the same time, open a PayPal dispute.
I once received a super fake as well -Dior- Sent it back for a second inspection and opened a PayPal dispute at the same time and indeed: After a week or so, it was accepted. Unfortunately and to my astonishment: The bag was put up for sale again by VC..... Incredible.
I read that there are some sellers who don't want to send the receipts along to VC.
I would NEVER ever buy any high end and expensive item without a -copy of- the receipt from VC: The seller has to blacken his or her details, so there's no harm in sending along the receipt.
As long as VC Quality Control is not 100% to be trusted, always ask for -a copy of- the invoice and always buy from trusted sellers and check his/her selling past. The latter is no longer possible via the app, but only by logging in on the VC site.
Good luck and let us know how you're getting on.
