Before you contact Sky, do the following which will give you information to pass onto Netflix:
Netflix hidden menu
Go to the Netflix app on Sky Q and on the screen with the random profile press the following buttons on the Sky remote:
Up, Up, Down, Down, Left, Right, Left, Right, Up, Up,Up, Up
This opens a hidden menu.
You can get the email address that the hacker used from the "membership" (Miembro) tab, and the service code from the "contact us" (Contactarnos) tab.
Netflix Live chat should then be able to log the hackers out of Netflix on your sky q box, reset the email address associated with the Netflix account back to your own email address, and send you a link to follow to reset password and PIN number on the Netflix website on your mobile phone
I am just another Sky customer!
