Overdrive Auto

I would like to congratulate these guys for providing the worst service I have ever received in my life. Brought my car in to have the muffler repaired in which they did a great job on. Was then told I needed some other work done which was new gaskets, plugs, wires and a control arm for my front right wheel. I asked if it was OK to drive in which stated it should be fine in the mean time until I get some extra cash. Stalled on the highway the next day. Took it back, They wanted $ 500 for a new distributor put in. I wanted to pick up my car have it towed to my house and replace the distributor myself. Called on a Friday was told my car was in pieces and agreed to wait an extra day to come pick up. Come Saturday they are closed. Called back Monday and my car is still in pieces. He then explained it would be around 45 min to get back together. Took it home, Installed new distributor and still no start. Spent days trying to figure out what it could be. Finally broke down and bought a new car. Sold my old car for scrap to a person who then tells me it was not starting because there was missing spark plug and runs fine now. Why was my car missing a spark plug when I got it back? I have no words for the level of frustration this business has provided for me.
