So, as i said, my friend bought 20$ worth of OnigiriCoins with my Credit-Card. Since i bought Onigiri Coins during the Beta and i had no problem, i thoguht there would be none as well for her, but there is a problem

The amount of Onigiri Coins (200+Bonus during a boost of OC) wasn't achieved to her account, DESPITE the amount of money taken from my Credit Card.

All the info needed, Serial ID Number(of the transactions), Credit-Card information at the time when bought(from the website), are in my hand(well on the computer), and i will request that Onigiri step up to give the amount of OC to my friend, or explain why they took the money and didn't give the OC.

This is a problem that has happened a couple times in the past since your post isn't the first I've seen about this issue. Send in a support ticket with your evidence of purchase and they'll probably fix up the mistake right away. (further issues such as this should be dealt with in the form of support tickets since they have very little interaction with the forums) This is just one of their weird wonky issue(s) of their purchasing that they either haven't noticed since they only occasionally pay attention to the forums or it hasn't been reported enough for them to begin taking care of it.

Yeah... I'm having the same issue. I bought OC and I sent them pictures of the transaction in the inquiry, but they still aren't sending me my OC, or responding. I hope they fix this soon...
