Calls three times per day and there is nobody on the other line. I called back and they have a recorded message talking about point redemption. they call themselves IP Guest.
asked for my boss by name. Don't know how she got the name, but no one talks to my boss unless he calls them, so when they wouldn't leave a message, that ended the call. CID says "VIP Gift", but I've had this on my CID before, usually for hangup or computer calls.
