BMW of Eugene

Brought my car in, they told me the problem could be one of two things, I ended up fixing both(to the tune of $600), Neither worked and they wanted to charge me for more diagnosis before charging another $1200. After arguing I went to pay and they tried charging me an extra $100! Service manager couldn't figure out why, took him 10 minutes to finally adjust the price, acting like he was doing me a favor. Then I get the car back(had to have it towed home), and the radio is missing, the dash is completely taken apart, there are wires hanging everywhere, and the thing is infested with ants! I couldn't believe it! Such an awful experience after they get you in the door. I can't believe they're still in business.
