Vestiaire Collective charges high fees to buyers and sellers by stating they have a team of professionals doing "Quality Control & Authentication". I will relate my experience and you can draw your own conclusions. I recently sold a 12,000 euro bracelet, with its original invoice and certificate. VC's Quality Control did not approve it because the "expert" could not read the invoice in English and got confused because there were two items listed in the same invoice. This the explanation I was given by Customer Service, I have written ptroof of this statement I make. The sale was cancelled, my 12,000 euro bracelet is still with them and their Customer Service chat is the worst I have ever experienced. After waiting 24 hours for a response, I got a standard message explaining that the "expert" got confused when looking at the invoice because there were two items in the invoice, and this is why the sale was ultimately cancelled. I hope this review can help others. I am just wondering, if the "expert" cannot read an invoice in English, can we really trust 100% that they are able to authenticate luxury items, in some cases worth several thousand euros? And if you have a problem, good luck getting an issue resolved with their Customer Service! Very disappointing experience...
