Just a friendly message to the OP....I stopped reading your rant about 1/3 of the way through....I expect the rep who got your letter at CO did the same, stopped caring about your issue and quickly prepared a form letter for you.

If you want to get a better response in the future, show a little care to the person who has to read your letter...be factual, hit the main points and keep it short. You'll get a lot further with this approach-- I speak from experience.
