ShyTorque..
A sobering tale and I (for one) am glad that you put your tuppence in.
Arguing over the RTF is unprofessional and probably a threat to safety in itself. Pilots need to be able to devote their mind to Aviating, controllers to Controling. Arguements are at best a distraction...
This is really the stuff of an MOR and I can only urge you to report it officially.(You can do this confidentially, as you will know).
Can I as (without revealing the location) was this a Full ATC unit or were to talking to an AFISO? (e.g. XXXX Information?). Either way it still needs reporting.
Best of luck
