just called, no response---then hung-up. This is likely a robot caller building a telemarketing list for later Sale or Use.
They are looking for valid phone numbers that are being answered & not rejected as 'no longer in service' etc.
I have been getting calls from this number, and also from 760-673-7240. They keep calling and when I don't answer, they will not leave a message. It's getting annoying now.
Gotten a call from this number and 7240, for a few months always the same no message left. However today the woman on the phone said she was from horizon power. Never done business with them and with the spam calls never will.
Horizon Solar in Hemet, CA is currently using that number for their telemarketing. They change their outbound caller-id quite often, and use at least a dozen different fake caller-id numbers to avoid being blacklisted here. They don't respect the do-not-call list, and they use spoofed caller-id, so they're probably not concerned about their reputation.
