Got a call from this number from Melody Ferris. I was not at my desk so she left her name and number - and that's all.  Just told me to call.  Since I deal with a lot of vendors and trade show people, I did try to call back and didn't get an answer or a machine.  Tried again a couple of hours later and some man put me on hold forever.  I finally hung up.  The background on "hold" sounded like Court TV or something, so I thought they might be attorneys but couldn't find anything in the phone book.  Started searching online and found this site.  

I'm in a small office and we don't donate to everyone.  My boss has charities he likes and that's all we do.  They didn't sound very professional so he won't be receptive to their tactics.

Thanks for all the info.  I'll know how to handle it if they call again.
