You got a strong point there, that batch is nasty with apple & nvidia finger pointing episode.
Ok double confirm your serial, find any relevance from apple support site to back up your model(if any)
Once you're full of ammo, try calling apple(1800-myapple?), dont sound frustrated, be nice but firm, hopefully they'll refer your case to their supervisors.
No harm trying to sweet talk(in a nice way ok not slimy or authoritative way), they are just like us, working our a** off, listening to customers whining all day in day out..
Remember the slogan.. "Think Different"... before bowing down @the repairshop's mercy!
