Hi @Anonymous User
Do you remember the three email addresses or usernames and passwords that you used ?
If so go to each account individually and cancel all active passes shown under My Account > Passes & Vouchers on here.
If for some reason you have forgotten your three account details then perhaps this article linked below can help.

Should you have no luck accessing all three accounts then see if nowtv live chat can assist you further.
