[Solution] to VM linking problem
This worked for me. Go to Bing Search (yes, it has to be Bing), and search for 'Virgin Media Register', and look for the first non sponsored result, which should be titled 'Register My Virgin Media Account' follow that which manages to stay on the original Virgin Media Registration page. Setup your virgin media account there. Once that is setup try and go to the normal login which takes you back to the VirginMediaO2 linking thing, and set up/link again. Credits to JSladen
