I receive calls frequently from 720-684-5373 which show up as "Unknown" on the Caller I.D. screen. They never leave a message, identify who they are or what they want, yet continue to call day after day. When I call the number back I get the message, "The number you have reached is not in service. This is a recording." From the 684 prefix this appears to be a telemarketing call center with an automatic redial system that is extremely persistent and annoying and needs to be stopped immediately from making further harassing calls of this kind!
