Can't transfer back for free?

So long story short, as me and my friends were looking through some Reddit posts we saw a thing about Ocean Week. Basically if you're in Oceania you can play with a ton a Champs in free rotation and you can earn rewards and what not. The problem? We were in NA so we went to the store and went to the account options and saw that it was actually free to switch to Oceania. We were giddy and we all transferred at the same time then we realized something was wrong. You can't switch back to NA for free, and since RP cards are region locked we are all screwed and stuck in Oceania! Is there anyway to reverse this and send us back to NA? Or are we doomed?
