What's the easiest way to book those painful government appointments without the website nightmare?

I'm a consultant who travels a lot and my passport expired back in February. Every time I open the state department site I get lost in the old forms, lose progress when I hit the back button, and close the tab out of frustration. Same thing with DMV slots , the calendars are never updated and you have to know the exact branch. I've looked for tools that can actually navigate these outdated sites or call the office, book the slot with my details, and confirm everything for me. Anyone found something, some hacks that handles these bureaucratic headaches so I don't keep putting them off?
