Hello,, ,,Microsoft?

I have this one console which must be a lemon or something and I need some advise. I got it last Christmas and in April I got the rrod. 4 months, huh, fairly quick I assume. I got the coffin, sent it back, received a different serial # so they switched it out with somebody elses used model. Sept. 07 I got infant drive mortality when it stopped reading games. Sent it back, got same console returned. When I took it out of the coffin I heard something jiggling inside. Put it up on the shelf as I had two consoles functioning. Forgot all about it. 4 weeks ago I had console three go out. With left me with one working console. Console 4. I thought  it should bust out the console on the self. For some stupid reason I loaded up GH3 which proceded to get quickly destroyed in the "new drive". Furious I call Xbox and start my tyrade. The guy on the phone this time was dumb as nails, didn't even have an xbox. He said they would ship a coffin. I asked him to just send a label as I still have the coffin from last time. He says he'll e-mail one to me the next day. 4 weeks later I'm still waiting. Who cares about a one month gold membership when you pay by the year and the console's been down for a total of three months at this point. Isn't there a lemon law on these or something. This console is way worse than the other three and has been in need of repair 3 times within a year. Shouldn't they replace it? I'm tired of buying xboxes and thought 4 would be more than enough. But I'm down to one. And that scares me. I don't plan on dusting of the ps3 anytime soon.

  Long story short, before I call back again does anyone know of a lemon law regarding these or maybe has heard of someone getting a different unit after three repairs.
