Abandoned Call!! Very likely the solar Telespammers / Telescummers are using a new spoofed #.
These creeps won't give up harassing us every day of the week and they care less about the useless DNC (Do Not Care) list.
No matter how many times you ask these a**holes to remove your number and stop calling, these pests will continue doing what they do.
All you can do is keep blocking the spoofed #s these parasites call from!
