Stuck on identity verification for my claim after 3 years as an electrician's helper

I do not have a current driver's licence and they want one. I have been trying to stay organised about it. Nobody answers the phone. What finally worked for you?

Check the list of accepted documents on the official site. Mine included things I did not expect, like a passport card.

Write down the date and reference number each time you try. They asked for it when I finally got through.
