First unemployment deposit is late, what should I check? after 7 years as a call-centre agent

I filed my claim 2 weeks ago after being let go as a call-centre agent. This is my first time dealing with any of this. I called the state line four times and only reached a recording. What would you check first?

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