If you send hundreds of low value bets to Magic Dice, you are spamming Magic Dice and draining our resources.
There are lots of accounts with a lot more Steem Power who could drain all our resources. We have to protect our service to provide a reliable service to everyone.
We have sent you a refund. You have to increase your bet size at some point or play less. The limits usually only get reached by bots.
