How to Stop a Transfer From My Bank to PayPal

1.
A banking customer service representative might be able to help you.
Contact your bank in person or via the telephone to explain the need to stop payment to a PayPal account. There might be a charge to stop payment.
2.
Placing your own stop payment online may work if done in time.
Place n on online order to stop payment. These often have to be done at least 24 hours in advance of the scheduled transfer. Stop payments will not work if the bank already has made the payment or if the stop payment does not process in within the bank's required amount of time.
3.
Paypal's help center answers many questions in various categories.
Contact PayPal. Contact PayPal to ask for reimbursement or if they will refund the charge.
