Who called from 3124486474

I got call from this number- the ID said Blue Cross Blue Shield. Not what my insurance is -But I answered it as I do for my business, and the girl on the other end said she got the wrong number very quickly. I thought it was odd so I looked it up and here I am on this page.  I'm guessing it's not really Blue Cross Blue Shield. Probably some kind of scam.

They keep calling and it is either an immediate hang up or no response the two times I answered.  

Rec'd phone call at 6:05 9/16.  Caller ID was bluecrossblushld.  Did not recognize the number and did not pick up.  The caller did not leave message.

Received 3 calls from this number in one night. All showed up as blue cross blue shield on caller id. No message left. Saw on another site that this is a "spoofed" number, so definitely not legit.

It looks likeit is from  Blue Cross & Blue Shield but if you look closer it is listed at Blu(no e)crossblu (no e)s. I did not answer and of course they did not leave a message.
