Sony :: CR Series Complaint

So I have this complaint I want to direct to Sony...should I type it our formally and send it in to see if I get any compensation ( etc etc..) ?

On Boxing day, I was working during the whole day, so my dad went to buy my laptop for me from the Sony Style Store (In Canada). I don't know what happened, but when I got home from work I saw my nice new-looking Sony CR series. I turn it on and quickly test it out...The problem is, it went straight to a log in screen with a random name "Naver". I signed on (First time using vista)... and all the timezones were set to Toronto etc.. and files were still on there.

I ask my dad and brother (who was also there) if the laptop was new. They said that the Rep that helped them said that it was BRAND NEW, and that it was a GOOD DEAL because it was like 200$ off from the original price.... (which is why they bought it, cause the specs are good for its price)...

The next day, I go back to Sony Style and find that Representative, I quickly explain to him whats happening with the laptop and if its really NEW. He QUICKLY apologizes and says that it was really a OPEN BOX laptop (which explains why it had another persons files etc etc.) So I asked if there were any more of these in Vancouver that I can swap or exchange or something (because this had some small wear and tear scratch lines on the inside). And he searched one up at another Sony Style. My dad goes and picks it up while i'm at work and I inspect it when I get home. This one was even worse, it had even more scratches, and was dirtier than the first one. So I obviously returned it the next day and they helped me set up a new windows..............
