Received a call to our land line a few minutes ago (10:37 am) today. Caller ID: Unavailable. Didn't recognize the number, but I picked up the receiver. I did not speak and held on in silence. In a few seconds a male came on and asked for my husband by his first name. I still did not make a sound. He asked for my husband 2 more times and then disconnected the call. An obvious robocall. If they can't include proper caller identification, they don't deserve my time, except to throw them off.
