Re-checking, there now seems to be a checker for NI contributions - YAY!!!
So, logged on - it wants your "Government Gateway" signon, so tough luck if you've never had to do this, you'll have to apply and wait.
- But not for me!! I have my signon
But now it wants further confirmation ..... by phone, mobile or app. I chose app, download Google Authenticator.
Use camera on the QR code displayed and type in number. No comment, presume OK
Then it wants to further check my identity. No problem, give Address, etc
Now it contacts a credit checking agency for further confirmation
Questions like "what Credit Card did you apply for in 2007"
Then, no warning, "Too many attempts" and locked out for 24 hours!!!!!!!
They asked for comments ...... steam was coming from the keyboard!! I didn't realise my NI contributions were more important than my Bank details!!
