the unexpected thing about Talking To Your Representatives is that it can actually work, if enough people are similarly mad about the same thing. you won’t get the elected on the phone. but they will hear about it from their annoyed staff, who might not have time to do anything else
You also have to maintain plausible deniability while being unbearably annoying: be pleasant to the office staff while wearing them down, or they'll label your number, name, and email, and just not interact with you at all.
