Many, many companies tel you they can give you all the information you want to know about this number FOR A RATHER EXORBITANT FEE!!! I don't think so. Also, if the people who call from this number do not have a sense of common decency and professionalism to leave a message which includes a name, company name, call back telephone number, and a brief description of the nature of the call, they do not deserve the courtesy of a return call (if they don't leave a number, where do you call anyway?).
