I have saved their number in my phone and whenever I am around loud noises and I am a bit bored I call them up, go through the prompts and leave them a loud obnoxious voicemail. They have already been treated to Skrillex, NWA and Ministry. I encourage everyone one else to do this and either blast loud music into their voice mail or fill up their voicemail box with meaningless blather. Until we start fighting back these calls will continue.
