Hearthstone - Goblins vs Gnomes - I bought the wrong packs - GVG ’m an idiot

I accidentally purchased the wrong packs for Hearthstone ’m dumb.... Edit: Blizzard is awesome and I was able to get a refund for the gold and money I spent on the wrong packs. Here’s the link to the video below of me opening the 50 Goblins and Gnomes packs.
