Who called from 7633679240

This is the Toll Free # for a health benefits carrier... PacifiCare.

I'm seeing a pattern here...hmm?? It appears as though this number is for Blue Shield of California...

I did not answer teh call, caller did not leave a voice message. I called the number but was always busy. Could this be a scam trying to steal identity?

This phone # continues to call my direct line at work.  I do not answer it they did leave a message and stated they were Ingenix-this is a company that we (Nephrology Medical Practice) order our ICD-9 and CPT books.

Call to my cell phone while I was unable to answer. No message, just this called ID phone #: 763-367-9240. No idea who or why they are calling a very private phone number.
