Abandoned Call - Caller ID shows: "Del Mar, CA" - Very likely more solar spam.
The local solar Telespammers / Telescummers won't give up harassing us every day of the week.
No matter how many times you ask them to remove your number and stop calling, these pests will continue doing what they do and thet care less about the useless DNC (Do Not Care) list.
All you can do is keep blocking the spoofed #s these parasites call from!
