You can only get a refund if it's the first time it happened and you weren't aware that you would be charged. If you are placing bets every few seconds then you will definitely get charged. You are only allowed to place 1000 bets each hour without being charged.
Cell N2 contains the number of transactions in the last hour. You can change your formulas to check this is below 1000 before triggering bets.
