Received a call from this number today. I didn't pickup. I figured it was one of those solar panel, home loan or whatever other scam calls are going around lately. Buh-bye!
My phone identified it as a telemarketer, so I didn't answer. Called back from my work phone (which displays a generic number on the other person's caller ID). All I got was a "goodbye."
Usually I don't answer unknown numbers, but I am preparing to present Financial Peace University and am listening to Dave Ramsey. So I thought, why not? I answered and there was that delay before the person came on. So I put the phone next to the speaker. Surprisingly he said hello over a period of a couple of minutes.
