Unfortunately, as a general rule, once a bet has been 'struck' (that is, placed and confirmed), it cannot then be cancelled.
For this reason, we build in a number of confirmation steps on the Bet Slip before a bet is accepted. This gives our customers enough time to confirm all selections and funds before committing to the bet.
In very rare circumstances, it might be possible to replace the selection to correct a genuine error. In those circumstances you can contact our Customer Service team via live chat immediately to discuss this.
This will depend on the bet that has been placed, however in most cases, the bet will have to stand as struck.
