Netflix hacked

Hi on Friday 17th October I received an email telling me that my Netflix email has been changed even though I didn't authorise this, obviously I was very concerned and was wondering how this was possible, I reset my Virgin email password and went onto Netflix to see how this happened and how I could change it back, I was told I need to get a service code on my account to change it back however I was only logged in on my two Virgin 360 boxes and the service code that was showing Netflix told me it was wrong, so I asked Virgin and they said they don't know anything about the service code, now I know people will say you need to speak to Netflix but I have and they just tell me it's Virgin I need to speak to and they can't do anything about this, like a lot of people the account language has now changed to Spanish and despite multiple calls and live chats none of the agents at Virgin seem to understand I'm telling them that a new Netflix account needs to be set up with my email and the old account deleted as the email has been changed on that account and somebody else is using it but they seem to think I just can't log back in and keep telling me to log in with my email but obviously because there's no account linked to my email it's coming up as no account linked to this address, is there anybody here who knows how I can fix this or speak to someone who can help me fix this as it's been going on for so long and every time they call or I speak on live chat I can tell they don't want to deal with the problem and keep passing me from person to person asking me to try things to fix it that I know full well won't work.
