to sort of piggyback off Leilleath’s post, the forums also arent a means to bypass ticket queues so if you have one open youll just have to wait it out.
also depending how recent your purchase was youre trying to refund can matter on whether or not you actually get a refund too, a sort of return period so to speak. There are no guarantees GMs will be able to grant one though.
Also might be worth noting to take a look at this for future references, you or anyone else browsing this thread. :Spotlight on: Game Master Help
