I can from experience say that Cub Cadet has EXCELLENT customer service. Dremil tool, Moen, Bennet, Canada Air, Boston Scientific, Google, TD Ameritrade, all my local hardware stores, my local power utility, and Flav-R-Pac also have great CS. And while ducking and hiding, I will say that the IRS also has excellent customer service.
The "less than useful" customer services I've run across include; DELL, HP, Expedia, Hot ticket, Century Link, Kodak, Auto Zone, Microsoft, Facebook, and Tracfone: The worst two players being, Tracfone and Expedia.

I can't understand a single word the CS person is saying.
