So far I have confirmed 6 times the availability of my items on the Safari browser for Macintosh, every time the window pops up open again to ask me to confirm, I tried to confirm on Firefox, all of a sudden they claim my eMail doesn't exist. I had this issue in the past, eventually it resolved itself, but it shouldn't happen in the 1st place! The website and the IT is a shambles, I am worried about having sensitive personal information and financial information on a website that is so careless with the IT. Any company relying on online sales does test it with every browser, every OS if the site is compatible, how come a company like Vestiaire doesn't do that? Customer service is plainly a shambles, nobody is ever responsible, meaningless copy and paste replies that show they haven't even read it. Yes somebody will pop up here and make a meaningless comment, pretending that they take the concerns seriously, but the same problems will happen again and again. Frankly I am wondering if I should not exclusively list on other platforms, where they take the IT a bit more seriously, apparently Vestiaire doesn't really grasp what a message such problems send to people who trust them to act as the middle man if they are buying or selling valuable items. I recently sold an item (for much more, I would like to add) with another website who offers the same as Vestiaire, there was a problem with the courier service they used and the item was delivered back to me, I contacted them, had a new label and a solution within the hours and could resend the same item with DHL the same day (yesterday), to the same location Vestiaire uses FedEx, the last time a buyer from France ordered something there was a delay of over 3 weeks. I am sorry but using the cheapest delivery options (I don't even want to start on Evri, the company who seems to lose parcels on a regular basis, or apparently used them for target practice - some of the parcels look they have been thrown out of a plane and then driven over for good measure, you can tell the sender used a sturdy box and packaged well, yet the box is squashed and has foot prints on it) and apparently the cheapest IT, it is not very trust inspiring! I for one will start using other sites more, for both, buying and selling and rethink if I might not delete my account, as the shoddy IT, total lack of interest from Vestiaire to up their service really makes me worried. If items go missing, despite that it shows they have been sent, you have to jump through hoops to get Vestiaire to act, which will happen much later, it would make a lot of sense if they would act immediately, when there is a chance to find out what happened and the person from the delivery firm who handled the parcel might remember, weeks later and having handled possibly hundreds of other deliveries, it's hardly surprising if items are never found and buyer and seller both are waiting to get their money, especially frustrating if you have bought something as a present for somebody's birthday!
