I mean, in general, a hostile tactic like this is likely to get the agent to do as little as possible as he can to help you while staying within the rules. Plus in many cases the front-line agent doesn't have the permissions to do what you need anyway and has to transfer you to a "supervisor" (usually not actually one) or a retention guy to resolve your issue anyway.
I’ve even heard of some centers that are allowed to hang up on you if you try that.
The call center I used to work for expected us to give one warning for such hostile behavior, and then simply hang up if the customer kept being abusive and/or threatening.
In general its, simply a bad idea to be rude to the person you expect to provide assistance.
We didn't have that, but people had figured out a way to use the hardware to hang up and bypass the monitoring and would just use it.
