I spent a whole afternoon but still cannot solve the problem, simply put, I was enrolling iPhone developer program, the single user one, when I reached a step "Review your enrollment information & submit.", it shows "Personal Profiles" and "Billing Info", however, in "Personal Profiles", the address is not correct, is has two lines, one is my current address, the second line is my address in China, I'm not sure why it shows a combination of my addresses, so I went to developer home page, change my profile, but it only shows a field of my current address in Australia, without any China address, I attached the screenshot, the blue line is my current address, the green line is my Chinese address. I tried to change address by clicking My Profile in "Hi, MyName | My Profile | Log out" in the developer's homepage, then it directed me to a page with title "Update your account information", under "Please provide a physical address. We cannot accept PO Boxes, APO or FPO addresses.", the address field only has my current address in Australia(blue one), but no green one. I recall that when the first time I was buying stuff from online store, it asked me to provide a payment method, I filled in my credit card number, but it told me the card is a Chinese credit card, which does not match my address(Australian address), so I filled in my address in China and changed the country to China. Later I bought a gift card, and change the country back to Australia with Australian address, but I'm not sure why my Chinese address is still there. Hope you can understand my problem, this really annoys me, thanks for any suggestions!
