Hello @dou_bou
Welcome and thanks for posting your question in the PayPal Help Community!
I understand your concern about sending money to the wrong person. You can cancel the payment if it is in pending status. If the payment is completed, you can contact the recipient to request a refund. You can also refer this link for more information on getting your back : What can I do if I sent a payment to the wrong person?
Hope this information helps,
Bindu
