I wonder what their "experts" actually have expertise in?
So far they identified a 40 year old vintage leather dress as fast fashion, then an item that was listed for 3 months already:
"Thanks for submitting this item to be listed on Vestiaire Collective.
After being carefully considered by our expert team, we were not able to list it
To ensure your next listing is approved without a hitch, here are some golden rules to create the perfect listing."
When I read "expert team" I have to laugh, they might be experts in banana peeling, but I think even that would task their ability. Their customer support is not existent, they authentication team seems to roll the dice, they specialize in sending auto replies apparently it is too difficult to actually read a request.
When they claim they are changing the fashion industry, it means they try to get you to sell expensive items for next to nothing, so they get their 15 quid. As a seller you are at the mercy of the buyer, it usually takes ages until a buyer picks up their items, however as the seller you have to send ASAP. They are totally full with shady buyers who try to switch items, Vestiaire is not even contacting you, all of a sudden you get a worthless item back! Vestiaire won't help you, one of their "experts" will tell you that your item was returned, even if the "buyer" returned a different item, or has worn and damaged it.
If you do have an eBay account, list your items there too, I guarantee you that you will sell much faster, with less hassle than on Vestiaire, and they actually have customer service.
You can't even call them, they have NO PHONE LINES, if one of them calls you back, you can't understand a word they are saying as they barely speak English, but I am sure for Vestiaire that is expertise as well. The delivery services they use are the cheapest and most unreliable ones, if an item on Vinted gets lost, it is automatically insured up to 500 if you use one of their delivery options and you get refunded, on Vestiaire you have to send them your passport in an email, and heaven knows what people can do with sensitive documentation, frankly I am sure that is a GDPR violation, as emails are considered insecure. Then you also have to supply the sending slip, despite that it shows as being sent, and tell them how your parcel looked and where you sent it from.... Then after 6 weeks you might get your money.
