iOS Developer Program: I misspelled my address, and now I cannot cancel my enrolment and try again
I would call Developer Support directly to get them to look at the specifics for your account:

Choose the Enrollment and Account link and sign in to get your options. It your AppleID doesn't work to sign in, then you need to contact the online store in your country and ask them to connect you with the developer support team. In the US it's 1-800-MY-APPLE.
