Horrible! Horrible! Seems automated. Just starts speaking blah blah blah. You can reply hello hello millions times but the machine just keeps on talking. Slam the phone down and next day same call again. Biggest mistake is if you pick up the phone to answer and say "hello". That's it. Now they know it's a live number.
Same as others reported. Claims to be Blue Shield, and they have "an important health screening" for me. No information provided, other than that I am to call 844-526-5589 for more information. Sounds like a scam to me. I will block the number. If it really is Blue Shield, which I very much doubt, they should be ashamed of themselves for making such a dumbass robocall.
