I might be 29 years old, I might have colored hair, and I might not be obviously disabled, but I am a legitimately disabled American citizen. Your airline had no right to treat me the way it did and your customer service supervisor was disturbingly rude to me in the face of my experience. I wasn't being unreasonable, I never swore, and I didn't raise my voice. I was trying my best to be polite and calm and I expected no less than the same courtesy in return. The fact that I didn't receive it and instead was made to feel as though I was just being lazy and irresponsible is beyond infuriating. I have to deal with Worker's Compensation and Disability about my age enough, the last thing I expected or needed was to have to deal with it from your airline when flying is already a painful enough experience.
Meanwhile the probability that Colleen or I will be flying United anytime in the forseeable future has just gone from small to negligible.
