I had got hacked a few weeks ago I managed to log all accounts out and logged off virgin profile. But you have to set up a new membership then on netflix as your email address won't be recognised but down payment for basic. Click back into virgin media log in you should be all be set up without any hacked accounts. Go into your netflix app cancel subscription...
But be warned Virgin are not doing anything about hackers as today the same account has logged back into my virgin netflix but this time I can't log it out as they've put a pin. Virgin have been far from helpful and despite being on the phone on and off for a few hours they till me it will take 10 days to rectify
