The reality is that no one can annul any bet on Bet365. Bets that are submitted must be kept from being deleted or canceled by players. Unfortunately, a high number of players make mistakes when placing their bets, or before the end of the match, they don't like their bet anymore or want to change it.
For reasons beyond our control, some card issuers may block transactions to gaming companies. We would advise you to contact your card issuer in this instance. When a debit card deposit is declined, the funds may be temporarily reserved by your card issuer and, therefore, not available to use.
