Hello, ldellicker. Thanks for reaching out to us. I can certainly assist you with updating the billing address. I was looking into the My Account app and website and it does not look like we provide an option to update it from there. I will pass along that feedback to the proper channels. Please send me a PM with your first/last name, full service address, phone number, and the address you would like the bill to go to and I'll get that take care of for you.
