    "Was a brand new employee about a 10 weeks ago and I could tell that Scott’s Directory had far more bells and whistles than I was using. Decided to give their helpline a try. Upon calling, I was greeted by a kind and bubbly phone assistant named Rabiya. She taught me how to create and save company lists. That action alone saved me a lot of time. She would take a moment at the end of every call to point out a feature I was not familiar with."
