We send an order confirmation email to the address you provided as soon as your payment is confirmed during checkout. If you haven't received this email promptly, please check your spam folder or ensure that you are checking the correct email account. After verifying the above two points, double-check the payment status on your bank or PayPal account. Occasionally, some successful transactions may not be immediately reflected in your accounts, so it's important to confirm their status. If the transaction is indeed successful, please contact us at support@perifit.co with the transaction ID, and we will assist you in tracking your order.
