I'm guessing what happened is the initial charge was just a hold - not a charge. When the charge didn't clear after a period of time, the bank returns the money to your account. That would be my guess anyway.
My friend in the U.K. had his order charge a week ago, he even got the "Your Rift is just about to ship" email but it still hasn't. He has a mid May estimate.
You will... The same thing happened to me. Ask them to review your order to make sure the order never got stuck on payment hold (which happened to me). Once they release it (which seems already has happened), they should try again shortly after as they did with me.. within days I had my Rift.
