I ordered a watch through Wish and after it never arrived the delivery date was extended 5 days, it never turned up so I applied for refund from Paypal. I got a refund within an hour. The watch was never seen. When buying from these Chinese internet stores you should always use PP. They come down on the side of the buyer 99% of the time. They pay you back then chase the vendor for the money. You don't mess with PP.
^^ This.
Also bear in mind, the vendors (usually with less than 3 star rating) try to keep you hanging with Bot replied messages with ridiculous ideas (Have you checked with your neighbour, maybe your postman left it with them) till the time dispute raising time is over and then they flay refuse to address any of your concerns.
During such time you may like to initiate a chat with Help bot and involve a human, share screenshot of communication you had with vendor. Till the dispute time is over, the human help will not really get involved but your 'concerns' are flagged which you can quote if need arises. OTOH, those so called humans are about as helpful as dill weed because they really have NO power to do/decide over anything; only a basement full of clarks peering over their terminals do the actual 'dispute redressal' but you never to interact with them.
With most of things chinese, usual caveat emptor applies as a lot is lost between chatbots and auto translation chats you have with 'humans'.
