I want to know how to confirm that my payment has been completed.

If you have received the order confirmation email, then your payment has been processed.
Please confirm payment details with the payment service you used.

If you paid using a credit card:
For regular orders payment completes 2 days from the order date.
For special reservation orders, payment completes 2 days from the first desired pick-up date.
