Some people no doubt today or yesterday got a text talking about a failure in authorising their monthly payment, and to go to the link provided, do not do this -- even if the text comes under Virginmedia and is shared among your legit VM texts you have received.
The site is not legit. And is designed to phish your account and bank details.
If in doubt email or, if you feel brave in waiting, call up to double check everything is fine. Only trust a website that starts virginmedia.com/ that way you know you are always going to the right official site.
