If you have sent money to the wrong person on Cash App, getting a refund can be difficult but not impossible. If the payment has not yet been accepted, you can cancel it by going to your Cash App activity and selecting "cancel the payment." If the payment has already been accepted, you can contact the recipient and ask them to refund the money. If they refuse or are unresponsive, you can contact Cash App support and explain the situation. While there is no guarantee that you will be able to get your money back, it's always worth a try to reach out to the recipient and Cash App support.
