Caller left message on my boss's voicemail stating something about a purchase order for $7,000 of heating fuel.  I thought it was legit, since our organization operates some housing programs and I was worried that maybe we missed a payment to one of our suppliers.  I called back on behalf of the boss, only to get a sales pitch about purchasing a subscription to a database that tracks government grants and spending.  Totally unethical to use a scare tactic like an overdue/fraudulent bill to get someone to call you back.  Don't remember the name of the company, only that the caller said his name was Dave Thayer.
