Did you double-click or refresh? Chances are the numbers will even out when you gain more points. You can try to file a ticket to see if a UA is able to help you, but they usually don't offer refunds for accidental purchases.
I understand! :) I would file a ticket so the UAs are aware and can instruct you so you don't get into any trouble.
Not overstepping Reya, but just wanted to say that I flipped your points back to normal. Just delete the scarf and we'll be fine.
If this does happen in the future, however - please file a ticket. A UA is best to handle this. I just happened to see this thread before the UAs reached out.
