I ordered a DVD off Amazon only when it arrived it appears to be in German. I think it says it has English sub-titles on the back but haven't taken cellophane off to check. (It's not a German film). I checked my order on Amazon and still can't see anything about it being German so I used the 'return this item' process, selected a refund and then got a message saying I can keep the item and they will still refund me. Is this right??
