I've been using Vestiaire Collective sporadically for over 6 years now. I've had some minor issues before but the company seems to have really gone downhill these days. I sold an item via direct shipping and the parcel went missing, I contacted their chat multiple times, was told a different story each time so ended up having to contact UPS and the buyer directly myself. I had to figure out on my own what happened, let them know, and they still refused to pay me out even though it was a system error and the buyer actually received the package a long time ago. Luckily the item wasn't so expensive but I will be deleting my account for good as their customer service is non existent and it caused me too much lost time and annoyance. For people considering selling items on VC - if everything goes right you will be fine. But if something goes wrong you're on your own and you will lose lots of time and maybe also some money.
