If a customer claims an incorrect charge or a duplicate transaction, first confirm the details of the transaction, including requesting for the screenshot of the payment.
If transaction was through Gateway Model, then check through your payment processor’s transaction history. If the charge appears twice or the amount is incorrect, you can initiate a refund or chargeback process.
If transaction was through Aggregation Model, then please contact our support team (support@pxp.io) for further assistance.
