Who called from 7189719353

Keeps calling and not taking. Finally I called the number back and got no answer. Caller ID says pharmacy

They called me at least three times today. I was home so there might be more calls while I'm out

Called ID had Pharmacy.  Nobody answered when I said hello.  There was a long stretch of silence then a female voice said goodbye.

Caller as barely audible and after I repeated "hello" there was only silence so I hung up.

Called and said my last name. Then I asked who is this? He just said... does anyone in the house has knee problems, back pain, foot, etc. I said no. Then he say have a nice day and hung up. They never said who they are.
