How long ago did you buy the Tier? It is possible that it takes a bit but shouldn't take longer then 1 hour if everything goes fine.
Since you were at the other server (in5) I have gone ahead and checked this for you. I will go ahead and tag our @Founder so that they can further assist you with this issue. Kindly wait for further response.
You used the donation option and not the option to purchase the rank. I will send you a coupon you can use to buy the rank correctly via private message in a minute.
