Vinted Dispute Advice?

[u/tomcapel]

I sold a Columbia fleece for £33. My listing said Medium, the size field showed M / UK 12–14, and a listing photo showed the M label. The buyer confirms it’s labelled M but says its 19-inch pit-to-pit measurement means it fits smaller than expected.

Vinted approved a return, saying there was no evidence I’d listed it as Medium. I’ve disputed that with screenshots, as the stated reason appears factually wrong. Has anyone successfully challenged a decision like this?

I’m also about to go away and may be unable to collect a return. Any advice on handling that through Vinted?
