I work for Sony.  I take inbound tech support calls for vaios, monitors, and sometimes tvs.  I hate this job.  
You may have already done this, LIC, but you need to get angry and ask to speak to a supervisor.  Not right away, let the rep get your info and document the call, then ask for a supervisor.  Not that this will help, but it may push things along.  
I\'m actually surprised they haven\'t been more responsive, though.  I guess it depends if you got your warranty through the store you bought it from, or an actual sony warranty.  There is a big difference.
