Received somebody else's package at locker

Shit, this is my first bad experience buying things online.

Two weeks or so ago I bought a Nintendo Switch OLED off somebody in France. For a surprisingly low price, not enough for it to seem too scammy but it was 10 or 20 euros lower than everyone else, and since the ad was barely a few minutes old I decided to take the gamble.

Fast forward to today, InPost tells me my package has arrived, yippee!! When I open the locker, there's a singular envelope inside, seemingly containing nothing hard, or at least tangible. Here's the thing, the sender appears as eBay under a name I don't recognize, the reciever is not me, and the package was supposed to be sent to a locker a kilometer away.

What are the chances somebody along the line took the switch and swapped it out? Again this is my first bad experience with Vinted, and in general, damn

I have reported this issue and they're looking into it. But damn I wanted my switch💔
