Who called from 6263336658

HVAC service scammer. Used "War Dial" technique to get around NO MO RO BO (hang-up and redial after each ring).
CID of "P"

I got the same call on the same day.  Did not answer.  Now I will officially block the call.

They called again using CID of UNKNOWN on the first two rings and CID of P on the last ring. Nailed by NOMO every time.

This number has called my land line several times. CID says Private Caller but shows the number. I don't answer because I don't know who it is.

Yes, still using CID of "P" and placing multiple parallel calls to try and fool NOMO.
