Unearthical/unprofessional mechanical work done at Multi Fitment Centre Parow .

I took my car to Multi Fitment centre parow for a service in march and thats when all my problems started. The car had no proble at all just that i wanted to to a regular service. The ladies there were very nice and told me the service cost and since it was going to be a holiday they would service it and i should come pick it up sartuday morning of the easter holiday.I specifically asked the ladies if they would be open since i had plans with the car and she gave her word that they would open fro car collection only.7am on saturday i was ther togetrher with onother client. The shop was not opened and the laddy did not even care to call and let us know.After sometime we managed to get her number at around 10am and she told us she is not coming , we were then stack at the garage with bags and my wife and inlaws.An hour letter a gentleman called me and accussed me of harrasing his wife.Imagine my suprise.He then came over after an hour and opened the shop. I collecetd my car believing the car is serviced and to my suprise that same night my clutch packed. Never had a clutch problem before. Took the car back and was given a 3000rands qoute. I asked what happened to this car because the car sound is different and it has a mis. NO ANSWER WAS GIVEN just they dont know.I kept geting calls about this not working that is not working .Things that were not even a problem before i brought the car to them.Finaly they told me the clutch is fixed but my 5th gear is not engaging. Then they told me its fixed. (MAKES ME WONDER IF THE PEOPLE THEY HAVE FIXING CARS ARE ACTUALY CERTIFIED OR QUALIFIED A MECHANICS).I took the car and my problems became more and more, the car mis now so pronounced , the petrol consumption so bad that on a 1.2Litre engine for 20litres i got only 100ks when before for the same litres i used to get avarage 220km.(this is a car that is suppose to have been serviced.)I then reached out to a local Fiat Certified Workshop and got the shock of my life.They told me there is about two things to check, 1 the lambr jet senser has been tempered with, or the spark plugs and the air fliter needs to be replaced, wich i dont understand because the car was supposed to have been serviced and this things replaced.Went back to the garage and was told the car needs an engine overhauls. (pathetic).Just asked my brother to pick my car up from the garage and we took it somewhere else. My advise to people out there dont do it. Cheap is very expensive.
