Intelius tells you that you can remove your general info (name, addresses, phone numbers) from their website. All you have to do is send them a fax (fax number provided at Intelius.com), but of course the fax number doesn't work.
Okay, so you can call their main phone number (425) 974-6100 but you are unable to get a live person. Not surprising. In fact, one of the numbers we punched in subsequently went to automatic "hang up." Furthermore, the associated fax for the main number doesn't work either. That number is (425) 974-6199.
Obviously, Intelius does not want to hear from the public; doesn't care about their own reputation. Recourse: contact the Better Business Bureau, your lawyer and Twitter!
