Hello Habil1364,
Welcome to the community!
Sorry to hear you're having issues changing your address online. Firstly, are you the account holder? I believe the one-time verification code would be sent to the main phone number associated with the account.
You should note this forum is community-driven and not intended as a venue for customer services. If you are having issues updating your address online, you might consider contacting customer service (see here). In addition, they can also be contacted via Live Chat, Facebook, or Twitter. Those methods can be accessed via the contact page posted above.
Hope this helps 😀
Cheers
