Who called from 6236964929

I answered and the call hung up.  Called back and the lady said it is Renewable Solar.  Blocked.

Answered call because we were expecting another call. Lady wanted to know if we new about solar on the ballot. Hung up and blocked.

Same.

They  called without leaving  a  message.  When  I  called  back  the  guy  immediately  asked  for  my  name  without  divulging  the  name  of  his  company.

A man calls and just keeps saying "Hello, hello", then he hangs up.
