I received multiple calls from this number. I called it back and got ahold of a real person. They said they were from the National Insurance Network. I sent a certified letter to the NIN telling them they'd violated the law, and they called me a week later stating that Health Line One, another company, was using their name in their telemarketing calls to avoid prosecution. I just called the telemarketing number back and they assured me they'd never even heard of Health Line One. I think they're full of it and will still be pursuing action against them.
