FCC approves new limits on automated telemarketing calls Under the new requirements, telemarketers will have to get permission in writing before placing an automated call to a consumer. Previously, companies that had an established business relationship with a particular consumer could call them without permission. For example, another FCC official not authorized to speak publicly explained, a bank could robocall one of its checking account customers to try to sell them insurance. The new rules prohibit that without written permission

Call came from someone saying that I had filled out application for health insurance. Told them that I hadn't. Person said maybe someone else had. Told them no one would do that. Person wanted to compare prices with my current insurance. Told them that they couldn't beat zero. Person hung up.
I called number back and a Bob answered. Was told that I couldn't remove number. Had to wait until I was contacted again.

Stop calling or the complaint gets registered with the DuPage and Cook County States Attorney. They know the phone company that issued the number and it has been 75 times that you have called me making it a felony now. It's apparent that you want to do me harm. So it becomes a felony.
