Call your Senators and Congressmen and tell them this shit is unacceptable.
Hello, Mr. Ted Cruz? I'd like to file a complaint abou.... Oh, go fuck myself? No, that's fair. I'll just dial Mr Crenshaw and... Nope, it appears I'm being told that this phone call is uncivil and I can go fuck myself. Okay, well, you'll be hearing from my vote in a heavily caged and gerrymandered set of districts.
Call over and over until their aides are sick of hearing your voice.
Daily screaming matches with some telemarketing company paid to handle their calls will do more harm to me than to any of them.
