I wouldn't judge the whole organization by one, or even two, personal interactions. Keep calling till you get a decision-maker (agree with @CathM3). Disability is tough... Not only must one deal with the physical/mental/emotional aspects, but also the economic and social challenges. These struggles are not made any easier when we encounter ignorance, intolerance, or outright discrimination. Of course, everyone must pay their bills, and that said... Some people/companies are more flexible than others when it comes to arrangements and schedules. Don't give up - fully explore all options and don't take anything personally (easier said than done, I know, but makes life much easier).
