bad workmanship, terrible warranty, and just plain rude service from Car service city Alberton

Please if I can give anyone any advice, please stay away from car service city Alberton, first of all you take your car in for a oil leak and ends up being a list of other problems, then you give go ahead to have your car fixed, you pay a very expensive bill, and your car come's back with problems caused by car service city, they replaced a rear mail oil seal for us and damaged the Crank sensor, which caused all the problems, they do not want to assist in any way although it is their fault, when you take the vehicle back they look at you confused and dazed on how that could happen and advise you to go get another opinion, then when you go for 3 other opinions, they still do not want to assist with paying back the outstanding invoice, where their technicians damaged the vehicle , when you try speak to the owner walks away, and sends his shouting wife out to shout at you, they charge you to come back after they have so called fixed your vehicle, so their warranty means nothing either, please if you want your car to break, then take it to them, other than that take it to any other place besides Car Service city Alberton
