Frankly a joke, sent my item, carrier picked it up, I keep on getting reminders to send it despite the fact that it tracks on the site of the carrier, sent them 2 mails, no reply not even the "We received your request" (the IT seems to be as bad as customer service) went on the chat where I talked to "Taylor" who claims to not be a bot but always gives copy and paste replies, seems incapable of seeing that i already sent the confirmation that it was picked up by the carrier, then ignored me, total horror show, the IT seems to be as bad as the customer support (and that is truly awful) as for their "authenticity checking" I think trained zoo animals could do better, they are as good as the IT and customer support, amazed that this company still is allowed to trade, they are remarkably useless and do not have customer support
