If your payment is taking a while to be processed and you want to cancel your beep™ payment, tap Refund Payment on the screen shown below.
You may also remove the beep card from the back of your phone. A prompt will be shown and you may tap the Leave and refund button.
Afterwards, you should see a confirmation of the refund. Funds would also be credited to your wallet again.
If you do not see these options available, please contact firstname.lastname@example.org for support with your refund.
