eh... no. You sent in a donation and in the "contract" upon purchasing it says that the kits and/or rank can never be refunded. No matter what happens you will not get your money back.
They've only been emailing for a couple of months? The EULA has been in place for what? 2 years? They are slow.
Wait, does this only happen on skyblock? You can chargeback on sky lock, just that you'll be perm. Banned forever
Ah okay. But you still get a refund. By the time EULA blacklists all the pay2win servers, blacklisted from buy craft wouldn't matter
You can actually ask @Wolf If you chargeback it will say when you buy on any Buycraft server it says "You've purchased too many chargebacks" You must appeal by emailing them.
