They are incredible horrendous, they now use Royal Mail tracked 48 for sending, twice now something went wrong with the scan, despite the postman having picked something up, instead of the confirmation mail I get that they couldn't pick up my parcel, you kidding me, Royal Mail has it, the idiot bot who claims to be customer service tells me each time to wait, then it shows as not sent, I lose my item. I asked the postman, he said he can confirm he picked it up, but it is the system, tried to talk to Vestiaire, gosh, almost like talking to a brick wall, they deliberately never give you a straight answer or do anything.
I noticed they even have stopped replying to reviews with their generic copy and paste BS, given up the pretense to care, but however they still send their shills to post glowing 1 liner reviews about how great Vestiaire is.
Btw be careful, they also change all the time their criteria, but never tell you, so the clueless and untrained who pretend to be authentication can knock back cheaper items to make their cut, because when it comes to high end, they are totally lost and about as smart as their customer service.
Total shysters, Vestiaire is not interested in the environment, they are interested in ripping buyers and sellers off, I think the only reason why they have a 1.6 star rating is because they send their shills to do the odd 5 star review
