Merge Academy: Rewards, Boosters and Sticker Book Issue

Treasure chests disappearing on Merge Academy. I am playing the special event in Merge Academy, where the focus is to get the treasure chest, at least for me. When I pulled one of my chests out of my storage cabinet and then clicked on it. It gave me the pink crystals and then disappeared. I was shocked, but thought what just happened? So, I pulled another chest out of storage ( I had 5, maybe 6, I can't remember now) The same thing happened, I got gold coins and then it disappeared. Over a couple weeks, I lost 4 chests.  I succumbed to the pressure of buying gem packs, a total of $160.00 worth, mainly because there is no way to make it through these challenges of the event, unless you buy more energy. I had barely ever bought the gems before because I figured I spent enough money on Pogo as it is. If it wasn't for the fact that I spent so much money buying the extra gems, I probably wouldn't have even bothered, but this isn't right. I spent the money and time to get to the treasure chests and Pogo, you need to make it right. I would like the chests restored to me, or a refund of what I spent, which I know you can confirm. Please, make this right. Pat E
