"We have received information from the California Department of Motor Vehicles that you may be paying too much for your auto insurance. Press 1 to adjust your rates, press 3 to be removed from our list"
Got same call as Emmy Y, called them back and someone answered. Asked why they were calling unsolicited, they offered to remove me from list and hung up.
So I called them back a few times and stated "since it's ok to call and annoy people I guess it is ok if I call back and do the same?".
