Playstation Customer Service

Absolutely the worst customer service experience I have ever had!!!!! For 15 days I have been dealing with 10 different agents on a defective Blu-Ray player only 4 months old. Each time, I am told something different and still no result. They promised to ship me the new unit and then I would return the defective one (only after multiple calls) because of the need to hire someone to dismantle and then set up new one to system, thus needing new unit first. Each time I call, am given a different story and set of promises as to "trust them, everything is now ok" and each time, nothing has happened. I want to talk directly to someone in the Sony Corporation who has some authority and can once and for all solve my problem.
