Who called from 2021110022

Who is this?

I have received several phone calls from this number over the last few days. The people on the line Barely speak English and are offering 7,000 dollar and 9,000 dollar grant from them government. It is a scam. And I told them so.

This number has called me several time recently.  There is a lot of noise in the background.  I can't understand anything she says.

This call seems to be generated after I used craigslist to post something. I do not put my telephone number in the ad, but state that "Please send me your name and number and I will call you".
This is the first time I answered in an email and sent my number accidently. Please note if you find your are getting calls from this number after issuing your phone number on craigs.

This is a spam number that tried to get personal information for me so they can steal from me.  I kindly told them what I thought and that wasn't honest, and the lady with an accent didn't like that I called her out and hung up on me.
