These solar people call me everyday from a different number, so blocking them would be useless. I will hunt them down and feast on their children if I find them.
These morons are calling me all the time, so I finally blocked them permanently......not even once did they leave a text or message !!!!!!! I do not know of anyone from area code 510, so I never answered any of their calls....they will no longer be able to butt into my privacy nor my unlisted phone number !!!! Good riddance to whoever these idiots are !!!!!!
