I am in the same boat, tried chrome, microsoft edge, my android Phone, and 2 separate PC's also tried clearing all browser cache/history etc, every time i fill out my name, account number and area code, click im not a robot then click register it just refreshes the page and goes no where.
I am due to be connected with virgin on the 2nd of April and need to get in touch with them on the phone however you need a password in order to access the phone services, but I can't access the phone services without the virgin media Account. I need to know the Engineer is 100% coming out on the 2nd with Corona virus going around because If they choose NOT to come out My Plusnet account is being disconnected and I lose internet entirely. Given the fact that I'm working from home i NEED the internet, yet I can't find any way of being able to speak to someone to confirm this.
I feel like im in an infinite loop of can't access X without signing up to Y but I can't sign up to Y and can't use X to find out why.
