got a call from this number, somerthing about property taxes. They mentioned something going on at Malcolm X college. I know there's such a college in Chicago, not far from VA Hospital. But if this was meant for Chicagoans, why does caller ID show California? I'm confused. This was a recorded message that played, & kinda cut off, hung up , at an odd point, or so it seemed.

Totally unsure about the purpose of this call.
