Can I get my money refunded?

Basically, I updated the game and was shocked to see that everything costed 30 gems for the new set since I thought they mainly would've been cash. I knew beforehand that in the coming weeks I wouldn't nearly be able to play enough to afford the adorable set before its gone (in gems), so I made the decision to buy the set with money.

My problem is, the gems were a bug and you can buy most of it with cash (which I could've done as I have enough). Now I regret spending the money given the fact the only reason I spent it was because of a 'bug'. Is there anything to be done? ☹️
