Just got a call from this number stating they were from CBRE customer service (my employer) asking me if I was working or not. I replied I was out sick and they asked who was working for me. When I asked who was calling they replied "Lisa from CBRE customer service". Seemed weird so I Googled the phone number and found this site. Something fishy is going on.
I got a call from this number and when I answered they had hung up. In a few seconds later I got a second call, and answered. When I answered it was from Group Health wanting to make an appointment with me.
So if Group Health doesn't know of this number than why are they calling me from it?
Often businesses have numbers that are used for outgoing only. That is the case with many of the GHC numbers. If they don't leave a message, don't worry about it.
