Cables stretching on a new road bike, help!?

Back in June I bought a new Scott Speedster S40 road bike. After about 20 miles of riding, the cables had stretched out so most of the gears didn't work properly. I took it back to the dealer, they proceeded to blame me for improper shifting even though this is my third road bike over about 7 years of riding without a problem. I took the bike back, used it for the rest of the summer, gears got a little sloppy but not right away. I finally just took it back for the warranty tune last week, and sure enough after about 30-40 miles the cables have stretched again and the gears are starting to not work properly. I keep crosschaning to a minimum, I ease back on the tension when I shift, so I just doubt it could be me. In addition to this, the bike has suffered from various squeeks/rattles/clunks that have needed to be fixed as well. Very dissapointing for a new $1000 bike. What should I do at this point, and what do you think is causing my gears to go out of whack so fast?
 
I would learn to do the basic adjustments yourself. It's very easy to do derailleur adjustments if you keep the cables clean and lubed. I have found the cable guide on the bottom of the bottom bracket gets gummed up and causes a lot of shifting problems. Clean the guide with a solvent and tooth brush and the cable. Use a dab of grease on the guide and cable, it will collect dirt on the surface but keep it away from the cable and guide. I use this site for information.
