Unable to log into my virginmedia account -error IDF-12B

Hello

I have been a longterm customer of virginmedia and can say that over the years I have had minimal disruption to my services and ha e only have to call support on a handful of occasions.

Two to three weeks ago we began having issues, whereby we could not access any apps this was coupled with a loss of broadband.  The broadband issue was quickly sorted. I later found out that there was an issue in our area.  As there was an issue locally I left phoning support for about week to see if things would sort themselves out. Unfortunately, they didn't.

A week ago I rang support and was told that the issue I was having was  " on our side and it would be referred to IT dept".  I left it there, however, the issue continued for several days after and now seems to have been sorted. 

I also reported that I was unable to log into my virginmedia account.  This  however error remains the case

See below screenshot of error 

Can someone look into this please

Many thanks
