Having some trouble with donation

Hi, I donated 10$ on my account for premium a few days back, and my brother decided to play with, so I made his account and tried to pay premium, I am unsure if there was an issue with my internet but the transaction wasn't processed and I had to reload the page after and do it again, however, unknowingly It had logged in as the "remembered" account, which was mine, and it paid for another 10 coins to my account mistakenly, is it possible that you could just remove the points and give the purchase to my brothers account instead? I don't currently have the extra funds to make an extra purchase because of this issue :(

hope to hear back soon, thanks!
