Scammed. GM in-game refuses to help. What do I do?

[tenebras]

I had an agreement with a player that they would pay me 25g if a raid they invited me to did not finish. The raid didn't finish, and they logged off without paying me. This is unambiguously a scam, is it not? The GM I talked to did not seem to understand how this was a scam and refused to take action. Sorry, is 25g not a big enough deal? A scam is a scam, regardless of amount, and if you tolerate any scams you are ruining the server.

Greetings,

Do you have screenshots of the agreement and subsequent events? If so, please PM me.
