says municipal call or hangs up

I got a letter from them in the mail saying I owed 144.12 for ambulance in aurora, il, december 29, 2003, we have lived in phoenix, az since march, 2003.  the lady was quite insistant that my husband was in aurora on that day and used an ambulance.  my husband is pretty much bed ridden and was in the hospital in phoenix until 12/25/2003.  tried to get a supervisor and she hung up on me when I called, called back left a message and no reply.

Got a call from 708-455-4046 asking to speak to "Melissa". (There is no one by that name that resides here.) She then asked if I would "take a message". I asked, "for whom?" and she said, "Oh, I didn't hear you, I guess it wouldn't make any sense to ask to leave a message if there is no Melissa there." (No kidding,unless she was trying to see if I was lying???) Anyway, I'm guessing they might be a debt collection agency? They seem to call every couple months. Very annoying. Don't know how to stop it since I've told them over and over again that no one by that name resides here.

yeap, it's a debt collection agency.  They call me every couple of days.  When I call back they are rude and hung-up on me.

When answering the phone with caller ID RMI MCSI 708-455-4046 it was an automated service requesting to "please call 708-455-4046 regarding an urgent business matter." When I returned the call the operator hung up on me when I said I was returning the call, and inquired as to reason for call.
