At some companies, reps are trained to trigger on phrases like "talk to my lawyer", "i'll see you in court" and "i'm going to sue you" and transfer you IMMEDIATELY to a legal department.

I learned this the hard way with a car moving company; from that point on, my account was tagged with a "transfer to legal" and I couldn't even talk to a rep.

YMMV, but mentioning legal action is one way to get yourself into limbo.
