Called on 10/31/16 at 2:38 PM. Asked for me by name, then said she was from Medicare Senior Services. I told the lady I wasn't interested and I'm not a "senior". She then asked to speak to my father, by name. I told her he doesn't live here...because he doesn't. Spoke to my parents about this and warned them of these scammers. They were already aware...thank God.
Please inform your older parents or relatives about this crap. It's just not fair. Scamming (#@kers!
