Did you talk to them at all? And since your name is job seeker, does that mean this number was an employer calling you back after you submitted a job application?
They called me three times this morning and didn't bother leaving a voice-mail. I don't know who or why they called me that amount of time consecutively.
They called 3 times this morning, a minute between each call. I finally answered the 3rd time, said they were calling to follow up about my social security eligibility (I'm years away). The call sounded a little robotic.
