Got a call from this number, too.  Did not answer.  No message left.  I do receive a fair number of "debt" calls because of two credit cards issued in my name by a company I used to work for that went bankrupt.  My lawyer assures me that, since all of my charges on those cards were demonstrably on behalf of the company, I have no personal liability for the balances on those cards.  But perhaps ... with the company legally bankrupt ... this is the only recourse the "collector" ("intimidator" LOL) has open to them ... go after the names on every credit card issued by the bankrupt company.
