Two hangup calls from this number in one day. Not someone I know

I was called,(Recording) "We have an important message for you".  (Call redirected) Live person  He gave me a name, I asked "Who is this?", answer, "Cris Matthews", he said (gave a name), I said "First name or last name", then he hung-up!  Boy is this irritating!

Got a phone call  asking for my 78 year old father. I asked who was calling they said ARS they needed to speak to him about a cell phone my father hasn't had a cell phone for years he is in a nursing home and has been for 3 years. I don't know how they got my cell number??? I told them he owes no one anything and to loose my number!!!
