Hi @DNF
Welcome to the community!
Sorry to hear that you're having issues with your Netflix membership. We were aware of an issue affecting some customers activating Netflix as part of their deal; this issue has been resolved and we are in the process of rectifying affected accounts. You should receive an email once your account is resolved with further detail. You should also see on your My Virgin Media account or app, a box with Netflix and the button 'Active', if you select this button it should take you to activating your subscription through Virgin Media.
