Called at 6:30PM on 03/15/13....Didn't leave a message.  Caller ID listed it as "Quadras Inc."

Yep they called me as well, i tried calling back and they ask me to leave a message i did not i will not give anyone information about me especially if i dont know who i am leaving it with, I THINK THIS IS A SCAM

Caller ID shows "unknown."

This number called here and tried to leave a message stating "every year seniors" something. I knew they were up to no good so I just half listened but they got as far as saying something about the American Heart then I turned my answering machine off and blocked the number.

This company is calling 1 to 2 times a day.  It is Senior Emergency Care.
