After you file

I got a call 2 weeks ago saying an advocate would cal me last week Tuesday. Never got a call. I called the number they gave me last Wednesday for the advocate no answer left a voicemail. Still ah ent gotten a call back. Not sure if they are “essential” employees so don’t know if they are open or not. But 2 weeks ago the lady that called me said my taxes were scheduled for the 28-29 of April. So idk if I should just leave it at that or call the IRS again
