Who called from 9203201992

This number calls every morning around the same time, I say hello, then hello again and it does not respond...then hangs up.

Yes, this number is calling me too.Already several times for 2 weeks.

Google search says it's Ameritech, a phone company, in Wisconsin

They called me asking me questions about my medical insurance and the health of my household. They were claiming to be "Medicare". I told them I not comfortable giving that information to them and they hung up. Definitely a scam.

They call daily.  I answer, the line disconnects.  This has been going on for weeks; tried to call back but the line rings once and disconnects.
