They're complete frauds and customer service is non-existent. I was sold a falsely advertised skirt. It was neither the brand nor even the size advertised. I immediately sent a detailed description and multiple pictures clearly showing the incorrect size (size large when it was adveryised as a size small), lack of brand (supposed to be Windsor), and very cheap construction (further inconsistent with the brand if they were to even argue that the tags had been cut out; no lining no store tags, the sizing tag is clearly not of the store, shedding sequins)They denied my request, ignored my additional appeals for help, and blocked me from contacting the seller. I posted a review several months later and was contacted by Mercari who after wasting much of my time... agreed to give me store credit that would expire in 30 days. When I said that was unacceptable they said I was abusive to their staff and that there would be no other offers. There is no customer support and the the "support" that exist are a complete farce. DO NOT USE MERCARI. If there's a class-action lawsuit against their unlawful asses, count me in!
