Wow, that is beyond frustrating! I have had many successful interactions with them. There was a period during covid where the payouts were beyond slow but other than that I've bought and sold some high end items and met some nice people and acquired some nice pieces. If you include a picture of the receipt (blacking out your personal info of course) as well as bag serial number that should clearly be enough for them to know it's authentic. I know I would rather deal with them than E-Bay 100 times over. But I'm looking to sell my LV Capucines BB never used so if anyone knows of other places I can list, I'd like to try somewhere else. Please post.
