Remember, try this only after getting rebuffed at the lower levels. Reasonably, this means talking to at least two tier one reps and one supervisor. Scenario being that you call a rep, get a bad answer, ask for the supervisor, they reinforce the bad answer, then you call back and try a different rep.
