scam artists!!!

I purchased a car in may of 2012 from this company. The day I took the car I noticed that the brakes were noisy and the muffler was hanging. I took the car back and They fixed the muffler and I was told the brakes were fixed. As soon as I left the dealership the brakes were making a clunking noise. I called and told them and the mechanic said the car just needed try o get used to the new parts. This didn't sound right to me so I called a different and well recommended mechanic and asked them. They said No and it's very dangerous to drive like that. I immediately took the car back to the dealership. I was again told the problem was fixed. The noise stopped for a couple weeks, then returned. I took it back again, and was told the same thing again. This happened a couple more times and They then told me it was my problem because I had put a certain amount of kilometers on the vehicle. They tried to charge me 180$ for the brakes. I have since taken the car to a reputable mechanic who informed me that the rotors were totally rusted and glazed over and that this was the cause of the noise. When their mechanic changed the brakes he only changed the pads. The repairs were not done properly and I was made to feel like I was just trying to scam them. I took the rusted rotors and showed them, along with my invoice which states what caused the noise. I was again yelled at. I then asked for a copy of the inspection report. They fought with me about giving that to me to the point that the rcmp had to be called.
