Hello! Ranks are permanent, so if you had diamond rank before, you should have it now, assuming you're using the same account. If you are certain that you bought the rank, you should make a donation support ticket, using the instructions on this thread: https://mccentral.org/community/threads/donation-issues.136/. If you have any further questions, feel free to dm me on discord (creeper7777777#6949). - Thread Locked -
