Our company got a call from this number yesterday afternoon ("Name Unknown" on caller ID) and the guy introduced himself as "Rick" from "Chicago Sunbelt."  Allegedly he had a potential buyer lined up for a business just like ours and were we interested in selling within a year?  I told him "no" and he seemed to accept that graciously.  The number may be spoofed because other sites had people complaining of the number being a company who allegedly made Facebook pages and someone else identified it as some kind of rental company.
