Follow these instructions, and report back how far you get, and what your results are :-
On your phone, tablet or computer, sign in to Now, and then select My Account/Manage Account/Now Membership.
Can you see a Cinema Membership listed?
If you can, can you access the new Wonder Woman OK?
If so, go back to your Huawei, and make sure you are signing in with the exact same account details.
Can you now watch the movie?
Set a Payment PIN on your account so that no-one but you can buy memberships on it.
Check your bank accounts monthly for any other unexpected payments to Now.
That way you can at least nip them in the bud, while you and Now figure out whose fault they are.
