Who called from 2161748675

Just received a call from 216-174-8675. No one on the line when I picked up. I assume it was a robo-call.

Another call with no message.

Definitely robo call, and it's an invalid phone number, you can't call the number.

No one there when I answered. I wonder why they even bother calling, except that it shows contact was made and they are now free to call again.

Called again and wanted to know something about my electric bill. I asked her to not call again.
