Called and left NO Message!  When number is dialed, the following phony, canned recording is played, " . . . you have dialed is not in service . . ." and call is disconnected.  This is clearly the work of a nefarious telemarketing entity that uses illegal cold-calling, number spoofing, and more illegal means to defraud people.  This number has also been identified by other services as being SPAM.  DO NOT ANSWER!

No vm of course. Blocking. All these scammers. Such a waste of time.

Calls many times a day. Never leaves a message. I don't answer calls I don't recognize.

No response on the other end. You can hear the boiler room in the background.

Keeps hanging up without saying anything
