Called this AM and asked for me only using my first name.  I asked exactly how I knew the caller as she asked for me by my first name and surely she would not be so rude and unprofessional to call a total stranger and do so.  She apologized for using only my first and then launched into her spiel and said she was calling to help lower my energy bill.

To which I replied, "And you probably did not check the Do Not Call Registry either before calling me. So, tell me why I would want to do business with someone and their company that is rude, unprofessional and disrespectful of my privacy.  Perhaps your company needs to rethink their telemarketing program and you should get a job with a more reputable firm."
