Who called from 8312321179

Just called my cell.  I don't answer numbers I don't know and they didn't leave a message.  I'm tired of getting spam calls on my damn cell phone!  I have a DC area code.  The area code of the number that called is Northern Cali.

Just called my cell. Really strong Asian accent asked for someone who doesn't own this phone then told me they had the right number and hung up.

Received call to extend my vehicle warranty.  I get a call from a different number each week, saying the same thing.  We see your vehicle warranty has expired, we can extend this warranty....blah, blah, blah... when I tell them that I already have an extended warranty and ask them to take me off of their call list they normally hang up.  Rude!!  How do I get them to stop calling?

Called my cell phone.  I rejected it. They didn't leave a message and I didn't return the call....never do if I don't recognize the number.

They call me continously even though I had asked them several dozen times to take my number out from their list. Also I listed the number to calling block  but they call me again and again from different numbers. How can I stop them?
