i baught something worth 4000 on a server called galaxite and didn't receive anything. galaxite staff told me to request a refund but i feel like they were supposed to give me my stuff
That servers staff are the ones to deal with that as they work for the server, NO ONE else but that server can help you.
This is why Mojang changed the EULA due to servers scamming players for real money, or kids spending on parents card for ingame items, which is not against the EULA
I personally don't like Galaxite, but I would recommend getting in contact with one of their admins, that's your best bet.
