You are not entitled to an interview for Tier II Offline Support just because you have good stats. Even though you are at/near the top of our project, you are not entitled to an interview. End of story. You never will be. No one is entitled to an interview for a higher/different position. Ever. Not even you, no matter how much you whine and bitch and complain and threaten to quit.
Grow up; you sound like a five-year-old throwing a tantrum because they can't have extra snacks even though they were good, as they were expected to be.
That is all.
