BTW before people come and try to tell me how to change my billing address, I know how to do it. I did it everywhere. It shows correctly everywhere on the websites, but as soon as Microsoft creates the PDF invoice that I need to send to my accountant it has the old address on it, despite it being updated EVERYWHERE. I gave up on it. I basically doctor the address myself and then take a screenshot of the pdf with the corrected address and send the image to my accountant so he stops annoying me that the billing address is wrong.
