So so BAD ....

I got a quote from Car Service City At Carnival Mall Brakpan to service my wife's car from . After me and my wife dropped of the car they did the inspection on the car and found all is in good condition. We left and I was later contacted with a quote much more than first quoted. They told me that the spark plugs is much more expensive. I asked them why did they not gave me the correct price the first time. Their response was that they are trained like that by head office to get clients in. I told them how can they charge me R500 more for sparkplugs than what Mercedes Benz does. I wanted to cancel the service then they wanted to charge me around R650 for inspection. I didn't want to argue further and told them to go ahead with the service but I told them that I am definitely not happy with how they do business. When we picked up the car my wife noticed that the pannel which contain all electrical buttons for the seat next to the driver seat was broken of. We confronted the manager and first he looked surprised then he said that the seat was like that when we droped the Mercedes of the morning. My wife immediately told him that it is not so. Even the Safety belt was not in its correct position. Also th driver and passenger electric seats were both moved to the front as far as possible. He then became very nasty with me and ask us to leave. My wife found a small flashlight next to the seat. When I asked the workers who's light it is they told me that it belongs to one of the workers that worked on the car. If they did not brake the seat then why was the flashlight there......what my thoughts is is that they broke the seat and used the flashlight to try to repair the seat because it was to dark to see what's going on under the seat and forgot to remove the flashlight. Why didn't the manager showed me the damaged seat or phoned me when he noticed the damaged seat. I emailed Car Service City's head office on the 19th of March. They said they will come back to me but until today I haven't heard from them. I also noticed that my wife's car power stearing fluid level was below minimum. I asked there head office why didnt they top it up or at least told me about it . They're response was and I quote "Please note that the service is not inclusive of checking the power steering fluid"
