This problem has been around for a long time, where people purchase premium through CC and have to submit tickets every single time to get their premium credited onto their account. If there is a problem with transaction process they should just disable it as a whole. But it doesn't seem like it is the case, because you can purchase Knight Cash with CC and it is insanity delivered. Also every time someone tries to purchase Premium, the credit card company gets charged on a spot. It is really stupid to have to wait when you already paid.
clannie waited 10 days and still no premium, nor responses from Customer Support.
