Not Receiving Coins
I've played and won several duels, but I'm not receiving any of the coins it said I won. My coins just keep going down after each duel.
Duel is a practice game mode that does not award coins for winning. Certain modes, like Tournament and Party, reward you for a win and it will clearly show a “WIN BACK” amount on the Play button. Keep an eye out for that to know which game modes reward a payout for a win.
I PAID FOR 15 MORE COINS AND IT DID NOT GIVE THEM TO ME TOW DAYS IN A ROW

I'm losing coins! I just noticed that the amount of coins I had drastically dropped without my using them.
