Multiple calls daily. Caller ID shows unknown 1-714-992-3590. I do not answer because of number of spam calls. No message is ever left. Major disturbance to my health and ability to enjoy my home.

Heating and air duct company - guy just rolled into his speal without taking a breath.  I let him finish then said no, I'm on the DNC list to which he acted surprised.  Come on dude...you know you hear that all day everyday!  I don't need air ducts cleaned or my furnace serviced.  What I do need is these scammers to stop calling me!
