The Free Bet amount is not withdrawable. If a Free Bet results in a win, only the winnings will be credited to the User's Sportsbook account - the Free Bet stake itself is not returned.
Example: if a £20 Free Bet is placed at odds 3.0 and wins, the User will receive £40 (£60 total return minus the £20 Free Bet stake).
The maximum payout from the Free Bet is £500.
