I’m trying to request a refund from apple,

I’m trying to request a refund from apple, I ordered things from my “Redecor” app. When I was trying to buy them at the time I had no money in my account so it held the charge then when my money hit it charged almost 100$ but I never got my rewards for my game, and I just want a refund.
