Received back to back calls (one on cell phone + other on landline) Left no message on either phone and the caller ID showed "unknown caller" both times. Called back and received a recorded message telling me they were sorry they missed my call and thank you for calling back. Hung up as not interested in purchasing Medicare Supplement Insurance or learning more about the changes made by the US Government that restricts my choices for obtaining reasonable medical care or coverage. _Claims_ I could push (1) to speak to agent now (2) to leave my name and number for a call back (9) be removed from their data base and no longer receive calls from them.
