Business ProfileforEdwards Nissan of Council Bluffs

I purchased my vehicle a few months ago. Per agreement I have 7 days to return the vehicle. I text them (before the 7 days) and told them I wanted to return the car because I was not happy, and the car makes noise on the interstate (I am on the interstate a lot for work and my kids traveling sports). They reposed back, we will get it fixed and bring it the manager already knew about that and the part is on order (never told me this, was they just going to call me out of the blew and say this when the part came in?) Long story short, I brough in the car to fix the problem, when I received the car back it was super glued, dented and taped together, looked way worse than before (haven't even made a car payment yet at this time). I messaged them and told them this was unacceptable, in addition, they damaged my car putting a black scratch and dent in it, I told them they needed to fix it, which they finally end up doing after I told them I wanted the photos of the proof I brought it in that way, they fixed and still left the dent in it, so I had to bring it back again. Also, the pillar on the window fell off on the interstate. I took the car back to get it fixed again because they did not fix the noise and they made my car look like complete ***. So, they then had the window guy work on it, he did a better job the noise went away for a week but came back again. Now they are refusing to answer my emails/calls. If I just returned the car like I wanted to in the first place, I wouldn't be in this stressful situation. They are very ********* and need to be shut down. Also to note, the sales manager that stated "Oh, no do not return it, we will fix it, that part is on order," he then stated he was done working with me/my vehicle but yet will not take the car back. How is this even ok to get away with? I have several documents texts messages/photos/video of a random guy saying my car looks like **** after they worked on it. but I am on my work computer,
