Who called from 213223126

SPAM! What I suggest is, to create a new Contact in your phone called "SPAM".Here you add any known spam number that is coming in. Set the attributes to this contact so the call will be redirected right into your mailbox without ringing. Likely that they will not leave a message.  This way you can eliminate repeat offenders to bother you again.

I answered the call, it's a woman looking for her dog.

Called me and i did not answer

I just got the same one just now, only one ring before ending.
Turned off my phone and computer...  paranoid like that lol
Can people access your info through your phone?

I thought it said to type your carrier, not who called.  Verizon was not the caller.
