Perhaps you have made a chargeback before / after purchasing your rank up. @Joe Henry is the donation manager - he should know what's wrong. :3

Hello,

Thanks for tagging me @Younisco.

I'm sorry but the 50SombrasDeExuZz is not a valid minecraft username, will you please drop us an email (support@cubecraft.net) with your Minecraft Username, Transaction ID & the date of purchase.

Thanks!
- Joe.
