Who called from 9712287076

I want to know who this number belongs to.

This number called no answer when pickedup... who is this?

Odd. Caller left an enthusiastic message in a non-English language. I think. No clue which language..or maybe just really unintelligible English.

she is a Korean lady and kind of annoying person...
talked to her 1st time about her situation but she is still calling to get more information which I don't have....
I told her to look up the internet but she is still calling me... and I ignore her call

I am getting calls from this number , sometimes several in a row....this has become very annoying , how do I get this blocked?
