While it is generally encouraged to properly scrutinize your bet slip before clicking on the submit/send option, you can easily cancel it within the first ten minutes if you mistakenly placed a game or you intend to modify a particular bet slip.
The fastest method is cancellation via SMS. To achieve this, Send “CANCEL#5454(this should be the BET ID NO)” to 79097 with the mobile number you registered with on Sportpesa.
In less than a minute after sending the message, you will receive a confirmation message notifying you of a successful cancellation process.
For punters interested in canceling their bet slip via the official website, follow these simple steps; log in with your username and password, click on “Bet History” on the right side of the screen, Click on the “More Details” option of the bet you want to cancel and click on the “Cancel this Bet” option.
