Obviously another scam (scum) caller.  When I called the number back with my blocked cell phone number, which would show up as an unknown caller, I received a recorded message that they were not excepting MY phone number at this time. Bwaaahahahaha!

Seems that the DNC-violating telepests are changing up their numbers.  Most od the crooks that called me today don't have too many complaints here - yet.
This moron called me at 11:38 am, in the same minute as a call from 8188600347. I wasn't home so I don't know if my robo call blocking service caught it.

I blocked a call from this unknown # on 5.5.16. CID = VOIP Caller.

"Culver City CA".....  Call, say nothing, ignore the screener's warning, and you get blocked! All scammers and unknown, unspeaking callers get blocked forever! Good riddance!

Something to do with air conditioning....blocked.
