My first unemployment payment still has not arrived after 12 years as an administrative assistant

I filed my claim 12 weeks ago after being let go as an administrative assistant. The page shows my claim as open but no payment date.

Keep certifying every week even while you wait. If they find you eligible, the weeks you certified are the ones that count.

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