Crown Gas Station review: Auto repair

To whom it may concern I was coming home from work I was two trafic lights from home when suddenly my car shook and stoped. I called the aaa they came and towed my car to the nearest crown gas station. My car had been there about ten days. The mechanic he s name is john didn't give me he 's last name he told me that the car is good working condition. But the car it shakes and stops whenever the car turn and stops. He charged me for parts $750 I ended up paying $1344 with the labor. I will give you a list of parts that he charged me for I went into different shops to find out how much the parts cost he overcharged me $400 for the parts. Control arm 1piece he charged me $150 it only cost $61.49. Suspension bal the mechanic charged me $100 it only cost$9. Cv adel one piece he charged me $160 it cost $71. Hub assembly $160 when I went on the car shops online they describe the hub assembly as being a plastic around the car but I don't need any replacement for that. Oil seal he charged me $60 and the most expensive in the market is no more than 15. I had been to this mechanic before few months back I had assistance though coordinated services [protected] and they had paid for me $1500 for repairs. I think there is something wrong there is some kind of fraud going on. Could you please investigate for me. The address to the gas station is 5929 leesburg pike falls church va. Also in my garage of what I own in the internet it shows that I own a 2002 jeep which was added within those ten days that my 2007 jeep has been in the shop. I don't know how to explain that could you please investigate for me. Also this area around the shopping area there is a heavy smell of marijuana and alcohol drinkers
