We are unable to change the billing address you gave in the order.
However, we are able to make changes to the commercial invoice. Please note that the commercial invoice will be automatically generated by the system after your order is shipped. As such, it will follow the billing address you provided in the order.
To change the address in the invoice, we have to manually do so.
Kindly send us a ticket to change the billing address in your invoice after you received the shipping notification that your order is shipped.
Nevertheless, kindly check and input the correct billing address before ordering.
