They left no message.  I called back, an auto-attendant said they were doing a Gallup Poll.

A female caller saying she was calling from USBank and knew my name.

Called my cell -- which is prepaid and I rarely use -- 40 minutes ago.  Didn't answer.  No message.  This is the 2nd call in 2 days.

My caller was a man who said he was from PNC bank ( we do bank there) and asked if we went to the bank last Thursday, I said we had no, he hung up.  ??  What was that about?  I had begun to get suspicious and would never give any personal info.  I never had a device call from PNC bank before even though I had talked to one of their new reps a couple of days ago.

this is PNC bank I called to make an online payment which was a mission and hung up after i was going to be transferred and got the call immediately. but never trust the number it can always be spoofed which can say anything on the caller ID.
