If you use Hide My Email, then Apple use some randomised email address to talk to Now, and the account gets set up with that email address, not your real one. Which is inconvenient at best, and catastrophic if you don’t know what the email address used was.
You best bet is to contact Live Chat, and see if they can figure out what email address has been used from you other details - address, debit card number and so on - and preferably change the email address for you to what was intended, or give you the wherewithal to do that yourself, or cancel that account, refund your money and start again, whichever is easier.
They should know what to do.
You can contact Now via Live Chat from this link:-
Chat online
Avoid ‘Get Help Quicker’ on this screen. This leads to the Nowbot, an AI bot that might well assist you in navigating the Help; but as you need to talk to Live Chat, you have already gone beyond that, and all the Nowbot can bring you is frustration.
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.
