These people have called me on average of every other day for a while.  I let the answering machine get it until 3/10/2015, when I answered.  They say they are a solar power company.  Very pushy even after I asked them to please take my phone number off their calling list.  On 3/12/2015, they called again.  I answered and again asked them very politely to take my number off their calling list.  I even repeated my phone number to them.  Again, they pushed even after I made my request.  I had to actually hang up on them after once again telling them to take my number off their list.  I was not interested.  Then again today, 3/16/2015, they called.  I told them this was the third time I was asking them to take my number off their list.  The guy actually tried to tell me that this was the first time they were calling!  After very sternly telling him to stop calling, and take my number off his list, while he was talking about why I needed these panels, I hung up. Then called back to ask for a supervisor.  The phone number says it is disconnected??
