My latest experience with Vestiaire Collective Uk has been horrible. I sold a watch (ref: 40366314) on 14th Jan 2024. I sent the watch together with the guarantee card and Vestiaire received the watch on 16th Jan. Then they asked me further proof of authenticity. Their online form asked me the date of purchase, I think it’s clear that date of purchase is the start date of guarantee. I am shocked they asked me for this info even they received the guarantee card. I then tried to reach them but it has been a nightmare. The CS chat never replies responsively. The email chat asked me again and again for info that I have already provided. And at the same time I received another email from their expertise team asking me for proof of authenticity…..BUT the so-called expertise’s email address doesn’t work. It seems to me inside the company they don’t want what each other is doing. It has been a nightmare. It has been a huge waste of my time.
