If you have got the new S22 range device with a participating promotion offer of the buds and Disney+ The below links are the ones to use to claim them
I did the galaxy buds through the Samsung promotion website but I only had to use the my o2 app to activate the disney+ on my account. I had to go to the my extras on my o2 and activate the disney+ with the email and it took me to the disney site and asked me for an email and password to open a new account or if I had one already to sign in to it to give me the free 12 months to the account I already had.
