Anet has told me no in every way possible. Even telling me they don't refund due to a bug issue of the item, which is so wrong. I still never got a refund. I did buy them from the gem store. In my opinion, we should have been offered a refund or an exchange if anet knew it would not function in home instance. I am very pissed. I may not buy anything again. Even might be time for a new game.
