Before sending money, always confirm the recipient’s information for accuracy. If you accidentally sent money to the wrong email address or mobile phone, you should attempt to cancel the transaction immediately. To cancel a send money transaction on GreenDot.com, go to your Transaction History, click “Cancel”, then confirm the cancelation. If the wrong recipient has already claimed the money, unfortunately the transaction can no longer be canceled and you should attempt to work with that individual to retreive the funds. Green Dot is not responsible if a customer sends money to the wrong individual.
