Political call reported by


This isn't a telemarketer, it's the Sierra Club, an environmental organization, here is their website: https://www.sierraclub.org/california/about-us If you are receiving a call from them it is because you signed a petition, signed up for a mailer, or otherwise put your email address and phone number into a box and agreed to let them contact you. My biggest problem with them is that I have asked to be taken off their list MULTIPLE times and my requests always go unanswered and ignored.
