Who called from 7206062387

They have called me twice, don't say anything and then hang up.

They called my house number at 9 pm when I answered the phone they hung up on me. Then when I called back to see who they were it went to voice mail.

A woman asked for me by my first name and said to remember to recycle, then hung up before answering my question- 'where did you get my number and what makes you think I don't recycle?'

Just called me, read a statement about the importance of something environmental, the guy spoke very quickly, then said to remember to recycle and hung up.  I now suspect that it was just to tie my name to the number, otherwise the call was pointless.  I'd really like to know more.

I just had my third call from them; these days, if I don't recognize the number on caller ID, I just ignore the call so they can leave a message if they're legitimate.
