Called several times and hangs up and doe not leave message.
Scam caller

2 calls space of 10 minutes no message.

Missed call, I called the number back. Number goes directly to pre recorded message and states will connect you to next available agent.. while you wait in music.
Definitely a scam

calls doesn't leave a message and hangs up if answered

keeps calling but hangs up when answered

Received a notification that I had missed a call from this number. I called it back on another number which went straight a pre-recorded message: "you may have received a call from one of our research agents... we will call you again when we are in your area". It never mentioned the company, and always went straight to the pre-recorded message, which makes me suspicious.
