Netflix/VM issue

Was watching an episode of a programme on Netflix where it glitched and came up with a code ui-800-3, currently I have been paying for Netflix but not via the VM bill, error kept coming up, so I signed out of Netflix and attempted to sign in.

However, the only way to get back into it was to link my email address to Virginmedia and put it on the account?

So to enable me to continue to watch Netflix I had to link my email to the account, is there any way to remove Virgin Media from being linked to my Netflix account so that I can pay via a different channel, as I do have a lot of credit on the Netflix account that apparently won't be used whilst it is linked to the VM account and someone else in the household pays for the Virginmedia?
