This is a harrassing phone call that leaves no message. It hangs up when I try to answer. I try to call back and the message states the voice mail has not been set up yet. I try numbers within 10 places of this location (i.e. 2401, 2400, 2402..) and receive same response or nothing. The only contacct is at 2410 and the voice call back name is very inaudiable. I left my numberr as a return number & am concern this is some form of Federal government contact that does not disclose identification. There is no reasoon it should not. I will no longer answer this number. The contact may be try to verify my phone number.
