caller trying to sell solar panel service, could hear others in the background in their office also making calls

Just called. CID shows Los Angeles . Didn't answer. Left no message

They keep calling to set appointments for solar companies to give me an estimate on having solar panels installed. I've asked them numerous times to take me off there calling list because I already have solar panels, but they keep calling 2 to 3 times a day, and this has been going on for about 3 months. Today they called again so I set up an appointment for an estimate. Maybe they will get the hint.
