I got a call and requested a supervisor.  The sales person said there was no supervisor.  I said I am on the DNC list and you are violating FCC law. (I made that up.) He said "Ma'am this IS the FCC".  I said "You are claiming to be from the FCC?" and the man said "yes".  That is ridiculous.  Then he asked me if I had hummingbirds in my back yard.  Nutty.
