I have ordered Photon in November itself. That time I choose USPS Shipping Method and now I wanted to change to DHL. How do I change it to DHL, when I go to the Celery Dashboard it is USPS and I cannot see any option to change the Shipping Method, I can only change the shipping address. May be @Steph can help me in this one.
Thank you @kennethlimcp, I send mail to firstname.lastname@example.org and got reply. Basically we cannot change the shipping method once the order is placed and processed and out of clearance time. I have been instructed to place a new order and send the new Order Number so that my place is not moved. I am placing a new order with new shipping method.
Thanks everyone for the help!
