Hi @Anonymous User
I don't work for NowTV but if you have three accounts and wan't to cancel any passes on the two accounts you no longer want to use in the future.
Then if you know the email addresses and passwords that you used to set them up, you will need to log in here separately on both accounts and cancel any passes that are showing active.
If you can't remember the two accounts emais or usernames used, then double check all your emails (including spam and deleted folders) for any nowtv email correspondence, together with looking at your sign in details on your playback devices that may give you some clues on what account names you used.
Should you be going around in circles or you want the two accounts removed totally from the nowtv data base, then live chat might be your best option.
