I didn't receive my TOTY BOX rewards.

 I played in TOTY BOX mode, the first load was free and I won 800 gems which I did not receive. I said to try a second time, maybe I will receive both rewards, I won 350,000,000 coins in the second game which I did not receive either. Please help, how do i contact someone and receive my rewards, it's about 350,000,000 coins
