You won't. You donated the money. Would you donate money to a orphanage and come back one week later, asking your money back ? No. So think of it like that, donation. Not purchase
You cant actually get it back anyways... The money already went straight to the HOST and was used most likely...
As far as I know, you cannot reclaim a donation however if you talk to crew maybe there is a way to get it back. After all, it is a donation. You didn't "purchase" the kit. You "donated" with the privilege of having the donor package.
As per the donation agreement, donations are nonrefundable. SkyBlock | Payment agreement Thread closed.
