Not sure if this is a bug or not but i donated on buildit and OITC about 30mins-1 hour ago and still haven't got the rank. Please tell me how long it takes Jezza1515
Try to wait a little longer because sometimes it takes a while. If it doesn't happen after a day, then send an email to info@itsjerryandharry.com.
like @YFIOTR said just wait or try to refresh your whole mc browser that might work aswell also why did you buy for 2 perks? thats 10 dollar (same as donator rank)
