Unfortunately once a bet has been placed it is not possible to cancel it. This is because when a player clicks on the button “Place bet” this would be confirmation that the bet, market, odds, etc would have been checked by the player prior to the placing of the bet. In addition, once a bet has been placed this would be forwarded over to the traders working for our sportsbook provider who would manually check and approve the bet.
That said, the vast majority of bets placed would normally include the option to “Cash out” of the bet which would allow players to recoup the vast majority of the stake. However the full stake cannot be regained via this method and due to trading decisions made, the option to cash out would not always be present.
