The monitor saga

Emi phoned Mitsubishi about my monitor. They said up to 3 failed pixels was OK. She then phoned Yodobashi Camera where I bought it but they wouldn't take it back. When she told me I was pretty irritated to say the least - £300 quid for a top spec "Japanese" monitor only for it to have a problem. I told her in the west you can either return it for a refund or for shop credit and have it replaced. Emi saw how upset I was and rather than do the Japanese thing - they said we can do nothing so there is nothing we go do - she stepped up a gear.
One day I came hope to find Emi on the phone. I knew it wasn't a normal phone call as she sounded very asertive. She had got through to head of Mitsubishi customer services how sounded like a stuck recored - I'm very sorry, there is nothing we can do. They admitted that altough 3 faulty pixels passes there quality control only 8% of monitors have any failure at all. Why should I pay the same as someone that has a OK monitor. Emi even threatened them with contacting the appropriate government agency but that didn't work.
Next Emi called the government agency for consumer affairs, they said we could do nothing legally but suggested we contact some electronics consumer industry group. They suggested we impress upon the Mitsubishi chap that a bad pixel on the edge of the screen was OK but one in the middle is not good enough.
Emi called up Mitsubishi and they folded straight away - they probably could believe that in the country where no one complains this women had come back for round two. Now the monitor has been sent to Mitsubishi to be inspected but knowing how the Japanese work basically this means I should get a new monitor - they wouldn't take it back it they were not going to do something. I await their response...
