Didn't receive my daily coliseum rewards yesterday

Both days I placed in the top 30, but the first day I didn't receive any rewards...

Can you please find a way to send me the missing 500 coins and ideally make it more consistent in the future?
Those rewards cannot just not appear nor disappear randomly, not when it's the main reward for this new mode...
It's already not very fun at all, at least give us the rewards we gained through our bought/hard earned resources :S
