First unemployment deposit is late, what should I check? after 17 years as a welding apprentice

I was laid off as a welding apprentice and filed right away, and I have been certifying every week. It has been a long 12 weeks. I called the state line four times and only reached a recording. What would you check first?

Thanks for writing this out. I went through something close to it 11 months ago, and it got easier once I kept a simple log of every call and form.
