Got scammed byuy a buyer who refund and send empty box

My wife basically lose 375 euros, she get scammed by a buyer.

She sell a doll for 375 euros, someone buy, she carefully prepared package , take pictures of everything, and sent.

The buyer get it, say an accessory is broken, ask for refund, then vinted directly refund her and ask to send back the doll.

She take a picture of a package, send it and when we got it, it was just an empty box with nothing inside.

Actually, the box we get is 100% different and the weight is only 0.06kg instead of the 3.5kg written.

The buyer intentionally ask for refund to send a empty box and keep the doll.

I get a proof from the transport company that the package is only 0.06kg when she sent it.

BTW, Vinted doesn't care, the support looks like a bot answering to me.

So i basically lose 375 euros + a doll (which is my wife passion), it really hurts.

Is there anything i can do ?

I already complain to police, bla bla bla, won't change anything, vinted just protected the scammer by directly refund her.
