....on the way to my second replacement? WTF

I just recieved my Playstation 3 back on Friday after experiencing the infamous Yellow Light (Had my PS3 since around Launch so I had to pay $150)....I asked for my Hard Drive back...they said they would send me it...but NO HARD DRIVE. They said I would get a new 60 gig Playstation 3, but ended up becoming a refurbished one. That day when I got it back, I decided to play some Resistance 2. After noticing some loud disc noises...I was playing online..and it froze......Then I updated Call of Duty: World at War and decided to quit and play something else. I clicked eject...but IT WOULDN'T EJECT!!!!!! It started blinking blue..so I decided to go ahead and reset it by holding down the reset button for a few seconds...heard the beeps..waited..started blinking not only blue, but not green! It wouldn't RESTART!. Finally I had to turn it off from the back and turn it back on...it worked. After contacting customer services via email..this is what I got....

Hello Matt,

..now I have to potentially send it in again..and wait....(I am waiting for inFamous......) I am totally disatisfied and pissed off. I invested $680 on this thing...plus $150 for "maintinence" which actually made the case worse. If I file a complaint..will I finally get Sony to give me an extended warranty and perhaps a Dualshock 3 for my troubles? I heard someone wrote a letter to Sony personally complaining that he spend a lot of money and expected a durable system..but for him it was no good. What do you guys think?
