Who called from 7798889383

Called and when answer machine came on he said hello, hello but did not leave message.

Called for Illinois Chiefs of Police. Wouldn't tell me the administrative fees. I even called back , He wouldn't tell me the fees or his name.

Keep getting a call from this number.  2 rings and then hangs up.  Calls start at 2 am, noon, then about 4 p.m.  Typically twice a month it happens, with 2-4 calls during aforementioned times.  No idea who it is.

I started getting calls from this number recently, and they do not leave a message.  I called back at 4:39 p.m, CST, and they said their office was closed.  Yet, the recording goes on to say call back during normal office hours Monday through Friday from 9 a.m. to 9 p.m..  Today is Wednesday.  Seems like a scam to me!  I blocked them!!!
