Wrong puzzle

So frustrated- ordered the cereal one because my daughter is high functioning- cereal is her lifeline and just went to finally do it and it's the candy one - with extra border pieces from another puzzle! What???!!! How is this possible? And I can find no way to contact the seller, reviews show they won't fix it or respond anyway. We are puzzle fans, but I'm leery now - this was our first White Mountain one.
