Who called from 2403890840

Got a call from this number today.  Not automated... she said something about calling in reference to some survey that I took about job opportunities.

I never took any survey, and I'm not looking for a job, so I said no thanks and hung up.

Number just called heard a strange beep and then they hung up. I had said hello twice prior to them hanging up. Very strange.

Someone (a male) said I took a online survey recently about looking for a job.

I said hello twice and then I heard a beep and it said goodbye

Received a call today from this number.  Heard a male's voice and the term "opportunity", then the call went dead.  Assume he wanted me to call back.   That's not happening. What an bone head.
