You need to go into My Account. Then, firstly, into Passes & Vouchers to see if there are a running Entertainment Pass, and a running Movies Pass, shown.
If there are, there’s your problem, and any attempted Cancel hasn’t completed properly.
But if there is just the expected one Pass running, next go into Bills & payments, and see if both charges are showing up there.
If not, then you likely do have a duplicate account running, with the second Pass Live on it.
Either way, you need to get in touch with Live Chat, explain what’s going on and what you have found, and ask them to sort it out with you:-
Get in Touch (all the options, and the best place to start):-
On a screen with big buttons all around, you may find the link you need is under a tiny green arrow, so be vigilant.
Live Chat and Send Us a Message:-
On Live Chat, when you can get onto it, keep your answers short, sweet and prompt, or it will time out on you.
If the person you are talking to doesn’t seem able to understand your issue, ask to be escalated to the next level of help.
