Scammed?

I bought all 4 campaigns ($4.99) then once I past the first few levels it asked me to buy the rest of the campaign ($0.99). I was positive it was going to say "you have already purchased this item" and allow me to continue, but it looks like a buck of mine just got sniped. Ill update this as I figure out exactly what a paid for, but this smells fishy...
