> "You must be disgruntled"

But you are disgruntled. You've got excellent reasons for being so. I always wonder why people will use things like that as stoppers for the discussion, the fact that someone is disgruntled alone should not be cause for dismissal, the underlying reasons are what matter. And you've gone over and beyond the call of duty in my opinion here and I am frankly surprised that Amazon manages to operate if they treat their employees like this.
