If you still want to talk to a staffer, remember that your congressperson has more than one office. In addition to a big office in Washington, DC, they will have several offices across their state or district. The DC office will employ staffers for various topics, but the local offices are just a few people. They’re also less busy. You’re a constituent if you live anywhere in the state (for senators) or the district (for representatives), so feel free to call any of the offices to get your message through.
