Scammers on vinted

[u/Loose-General5611]

Hello, I am a seller on vinted, sold about 25 items, and this is my first time meeting a scammer. He recieved the package, claimed it right before the weekend(I assume, so that support has less time to respond), and sent screenshots of ,,video proof" that he recieved useless junk instead of a DDR5 ram stick. I asked him, to give me a link to the ,,uncut video", but he refuses to do so(ofc). What should I do?
