Jenny Conway's List of Companies That Can Go Right Straight to Hell:

BANK ONE -- for unnecessary fees and lack of empathy.
FRATERNAL COMPOSITE -- for careless, intoxicated photographers, contract scamming, and incompetent people answering phones and scheduling.
HYUNDAI -- for not EVER fixing my window, and then employing service people who talk down to me and imply that my window should whistle loudly and hurt my ears because it is "normal road noise."

I feel like there are more, but those are the only ones I can think of at this moment. If you have a company you would like added to the list, feel free to let me know and I will add it, ***for no additional charge***
