What do I do if an artist from here took $325 of my money and left?

If it was throught paypal, I think you can ask for a refund on the app. also, report the user on the discord server, so they can ban them

It was boosty.

damnn, that's an issue, I'm sorry this happened to you:(

It was a bunch of YCHs, over a long period of time, and I found out today I was blocked by them on discord, I cannot get a refund due to boost being boosty, am out $325, have no idea how to fix or even deal with this, and if anything, I am unable to deal with this and am now just a cautionary tale. Kind of ruined my ability to even really trust artists without holding onto my money until everything is done... I can't even get onto the YCH discord because I keep getting an error from my device.
