First unemployment deposit is late, what should I check? - what worked for you?

I was laid off as a school bus driver and filed right away, and I have been certifying every week. Thank you in advance. I called the state line four times and only reached a recording. What would you check first?

Keep everything in writing and save the confirmation numbers. It saved me later.

When I finally got through, the agent said my employer had responded late. Once that cleared, back pay came in one payment.
