Not literally hang up the phone, but when I worked in CS in a PC repair store, if someone mentioned lawsuit, small claims, courts or legal issues, I’d stop them immediately, and tell them that our management would be in touch with our legal details, and terminate the call immediately.

At that point, the onus is on management/legal to decide whether the threat is credible or not, but you don’t have a slightly above minimum wage kid getting everyone in trouble then.

I would expect a similar response from almost any CS representative for most companies.
