Who called from 9543425115

Called my cell phone and left a blank message on my voice mail.

They just did it again.

Called and hung up without leaving a message.  Third time. Going to block them.

This time the call went straight to voice mail.  It was a blank message.

I answered thinking​ it was my dealership calling since I had just bought a new car 2 days prior and a woman was on the other line. She didn't introduce herself or even asked to speak to anyone. The call lasted 12sec. There was about a 5 second pause before she said another word, it seemed to me like she was trying to listen in on the back ground like fishing for information, to get a name or something (weird). I very quickly told her she has the wrong number and I hung up.
