Who called from 3143642000

when I try to call this number back my cell phone states this service is unavailable??

When I called this number back, my cell said 'The number you dialed is not a working number, please check the number and dial again.'

I get call from this number anywhere from 4-10 times a day. And when I call it back it won't stop.

Hey, this number is St Johns Mercy Medical Center Human Resources phone number. It's just a general phone number that pops up on your ID and is one of many lines there, however if you try to call it back, you have to enter the persons extension number instead of the 2000.

The number is not valid.
