Account balances are adjusted to reflect any pending wagers you have, including future bet propositions.
Customers cannot risk more money than is available in their account. Even in situations where you have a pending bet that you know for certain will be a winner, those funds cannot be used to place bets until the wager is officially settled and the winnings have been added to your account.
It is the customer's responsibility to verify their account balance upon each login prior to wagering. When you verify and accept your betting account balance, you agree that all previous transactions are correct. Claims or disputes must be reported at this time.
