Item refund

Hello. I've bought wrong item, I want to make coin refund. I checked http://forum.warmane.com/showthread.php?t=318954 and http://forum.warmane.com/showthread.php?t=302382 so I created a ticket right here https://www.warmane.com/account/support but there is no answer. I bought the item about 19 hours ago and created the ticket about 8-9 hours ago.
What should I do?

Nothing, sit and wait.
It's only important that you make the ticket within 24 hours of the purchase, doesn't matter when they get around to it.

Okay, thank you for your attention
