You had the chance when Collin announced the server was blacklisted and most likely staying down. Since the server is back up, or going to be, you have to follow the Buycraft Terms & Conditions, which states "All refund requests are at the discretion of Minetime LLC." I'm unaware if you can still email Collin to request a refund or if you have to wait until NoobCrew or CypriotMerks announce how they plan to run Minetime.
In order to receive a refund, you need to provide us with a valid refund request reason. You have not provided us with a valid reason. Furthermore, as per our payment agreement, we do not issue refunds on payments that are more than 45 days old. All the payments you made to us are more than 45 days old.
