Who called from 2062031084

I got this call twice and answered it and no one answered me back. I called it back and it told me that it was an international call that I couldn't make.

Didn't answer

I did not answer it twice.

answered, said Hello a few times, telemarketing. "Getting back to you on how to make thousands in cash" blah blah.

they keep calling my cell phone and i just hung up, but they call everday.
