You agreed to the terms and conditions of making a purchase when buying an item from the store. In these terms and conditions, it is stated that InvadedLands does not issue refunds and you are not allowed to charge back your purchases. Doing so anyway is in direct violation of these terms that you agreed to upon completing the transaction. Making threats to disobey the terms and conditions of a purchase is not going to get you your money back, nor is it going to get you unblacklisted.
Rethink your approach to this situation and appeal your blacklist once you have thought this through. Have a good day.
