I Felt the greek Squad rip me off ?

I felt that the Greek Squad rip me off because my computer screen went black and they said that it was an installment problem and it can be fix in about 2 days. so they charge me 200 dollars to fix it. I had to pay up front before they started it. 200 dollars I was charge just to install the windows xp back on. Ok then they call and told me that they had find another problem and it was my cd rom causing the problem so I told them that my cd rom worked find before I bought it to them. and when they told me that my wire in the cd rom was burn out and I knew that was a lie so they told me that you have to get a out side cd rom were I would have to hook it up to a usb port for about 89.00. so I told them NO that's ok. And then they call back and said that it was the video card so I had to pay another 90.00 to fix that and I got so fed up that I said give me my computer now. So NOw my cd rom doesn't work and NO the cd rom wire was not even burn so when I told them they said that it was the part to hook the wire to was breaking. I was so angy Never again will I ever take my computer back to the Geek squad again. How can they sleep ripping people off. They had my computer for about 3 weeks. What a waste.
