Refund in gems
No one on here can do anything, open a support ticket.
If your ticket has been untouched for 3 days, there is a sticky about what to do.
As DavidSev said, you will need to contact support. I gather from previous posts that there is a cutoff time for allowing these types of refunds and if memory serves me, it’s not a very long period of time. So whether or not you get a refund will depend on if you meet the requirements.
