This sounds like a situation I was once in with OC. Had a completely processed order where my card was charged and a shipping label sent. The label didn't update for half a week, so I emailed them and was told that the item I ordered was sold out and that my card would be refunded. That seemed like something they should have contacted me about, as opposed to me contacting them. At any rate, I hope that your situation turns out better than mine did.
