I'm sorry about the issue. Does it recognize the old post code when resetting?
Can you please confirm your btinternet email address?
Do you have windows xp, vista, or 7, or 8, 10, or mac computer?
Can we do a remote support session, so I can troubleshoot the issue directly on your computer together with you?
Please reply at the box below. Thank you,
Please reply and let me know if you still need assistance with this after trying the old postcode, as that is the one that is still registered with your account until you recover it and update your information...
