Who is this

Auto glass company cold calling.

Called my cell during work hours. Caller ID was Phoenix, AZ. Did not answer. Caller did not leave a message. Blocked number. Have gotten many calls in the past from an auto glass company, so it's possible that this might have been them.

Nation's Best Auto Glass. Cold calls despite the DNC (Insert audience laughter here).

They have called many time, fairly frequently.  You have to go to the DNC list site and submit a complaint right away.  They can be fined.  They harrass and are rude and disregard repeated requests to remove name from list.   Report them, then block them.
