For some reason, I can't claim my rank on the website, even though i have logged into all the server and put the right In Game Name. Unfortunately, I can't upload evidence of this, because for some reason, the thread won't upload my picture :/
Or simply ask a staff member. That will work. You see, I have a friend, TalentedTyler (a.k.a. xxKing_Tylerxx a.k.a. da_bus_man_2) , who lost his Sponsor. So, he asked a staff member so he could claim it back. Probably that will work.
This typically means you did not purchase that rank. You will need to provide a copy of the receipt for the purchase. Whoever paid for sponsor should have received an email. You can send this in a message so you don't post personal information on the forums.
