Who called from 3604609918

Did not answer--no message left--I did not call back. Few people have my cell phone number.

They called my cell number and did not leave a message.  To me is has to do with Facebook because when I sign up on a particular app it does ask permission to access your Facebook info. and of course, my cell phone is listed in my account.  I did this two days ago and sure enough this number has been calling ever since.

Called ... hung up when I answered.

This call comes through on my cell phone number. So not know this number and the area code is was the west coast...seattle area.
