Transmission tube fracture recall #12138/ How my Chevy nightmare continues

I bought a certified 2010 Suburban. I bought a Chevy because I wanted to buy American I bought a certified so I know I was getting what I paid for. Boy was I wrong. The Chevy dealership didn't do half the things that was supposed to be certified. I'm no mechanic, but I have a good friend that is. right away he noticed the mismatched tires, the bent running board, the rust on the brake rotors, Etc. When I contacted Chevrolet, they were helpful but it started a two-month ordeal of back and forth with an angry dealership. Regional service manager got involved, Real mess. Well now I have a fractured dipstick tube. When I call Chevrolet guess what they told me? It was already fixed by this thief dealership under a bulletin/recall # 12138 and they couldn't give me any more information because it happened before I purchased it. My mechanic says it was not fixed properly. Instead of replacing the entire dipstick they cut it in half and replaced 1/2 to the other half. I would expect nothing less. I'm sure they billed Chevrolet for the whole job. Theres NO WAY a dipstick tube should fracture twice in a 6 yr period. I took it in to a NEW dealership while i was there for my engine powering down with my 4 young children in the car endangering there lives on a dark highway at night. That was a throttle position sensor recall. How many times can i be disgusted with my decision to buy a Chevrolet.

The new dealership indeed agreed that the transmission dipstick tube was repaired and is again fractured. They said i should take it back to the thiefs. I told them that bridge is burned. They then told me they could bill me for 7 hours of labor to replace it. A full day to replace a dipstick tube.? Does anyone have any suggestions before i start posting my dilemma on as many forums as possible?
