Contact @Joe Henry and be patient.I bought a obsidian rank, and i'm waiting 45 minutes and my rank is not here. pls fix it i paid much money.
You can also contact Joe Henry here or on Discord. It may even take up to several hours until your rank arrives, so I suggest you to wait a few more hours until you contact someone about it. Sales@cubecraft.net and @Joe Henry will both help you out. If you may have other questions don’t hesitate to contact me or another staff member.It does take time for ranks to go through. I do suggest emailing sales@cubecraft.net and explain to them what's going on.
Good luck!
