Stuck on identity verification for my claim - what worked for you?

I was asked to verify my identity and the site keeps rejecting my photo ID. Nobody answers the phone. What finally worked for you?

Thanks for writing this out. I went through something close to it last year, and it got easier once I kept a simple log of every call and form.

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