Have you asked her point blank why you weren't offered that deal?

This seems very weird to me and if she is pissy because you asked for money so, she decided to give the money to someone else, you should at least hear the truth about and/or have her boss hear the truth as well.

As much as I hate getting into things with my bosses, I always feel better afterwards to have had "the talk". I think it is very important for a working relationship to be able to "talk things over" with your boss and/or their boss. VERY important.
