Vinted refunding scammer €150 / Any way to hold Vinted accountable?

I am completely drained from battling this so I will copy+paste my email to Vinted below if that is okay so you can understand the issue. I reached out to support and also to legal@vinted but they keep sending me copy+pastes and closing the case. Despite me showing 100% clear evidence, and all the facts objectively being impossible to see in any different way than what I’m telling them.

“Good morning

I am on Vinted with this email and under username [username]

I sold a brand new perfume on your platform after already selling 50+ times, with a perfect 5-star score.

Upon arrival, the buyer claimed that the perfume was damaged, and escalated to Vinted. I followed up to her with multiple questions, and she claimed the perfume was 1. leaking and 2. did not spray anymore. Because of this I accepted a return and paid for shipping.

Upon return, the perfume was NOT damaged, the spray was working perfectly, and it was not leaking. But the perfume wàs used. I shaked it up and down over a piece of paper and nothing came out. I took photos and videos of the spray working absolutely fine. Conclusion: The buyer bought my perfume, used it, decided she didn’t like it, and lied to me for a refund.

I very clearly expressed this to support and wrote a clear and concise explanation, and added evidence. I even told them that I have clear videos showing that there is no leaking or issue with spraying and to let me supply them. I also added the videos to this email.

Marwa from your Customer Service then, without even inquiring further, sent me a copy+paste answer that had nothing to do with my issue, closed the issue, and refunded the scammer in full. I asked to at least refund me the return shipping costs that I paid for the scammer to return my item, but I keep receiving copy+paste answers, and Marwa keeps closing the ticket without actually answering.

This is unacceptable, Vinted is facilitating scammers. This way people will just buy brand new cosmetics, decide they don’t like them after all, lie, and return the now-used cosmetics for free.

I added the videos where you can see the perfume works perfectly and does not leak. I need compensation and definitely need to be refunded the return shipping costs that I had to pay for.

Thank you”

Response from Vinted this last time:

“Thank you for your patience.

After comparing the photos you sent to the damages reported by the buyer, we concluded that the same damages were reported by the buyer when you accepted the item's return.

Take care,

Alona || Vinted”

The whole point is THAT THERE ARE NO DAMAGES and I’ve shown this to them in VIDEO EVIDENCE, how are they able to live with themselves being so nonsensical? Is there any way I can hold them accountable or get help?
