You're not necessarily wrong, but I can't help but think that it may cause further frustration for me if I'm trying to convey a certain sentiment of frustration (for the sake of the argument, let's say that I'm not being an outright asshole at this point) that may be lost on the rep that I am talking to, resulting in a misunderstanding, which would further irritate me and escalate the situation.

There's genuinely something to be said about honesty and accurately understanding someone.
