If the customer is right, simply accept the chargeback. If they are wrong, you can fight it by submitting evidence to your payment processor. Gather tracking numbers, delivery confirmations, customer emails, or signed receipts proving the purchase was legitimate. \n\nAdditionally, try contacting the customer directly.
