Disappointing service & Overcharging labour

Possibly the worst service I have seen. My girlfriends car was at Ford Hatfield since monday morning. Today is Wednesday and the only feedback we got was when my girlfriend phoned in to hear what's wrong with the car. It took them three days to do a diagnostic test and rep**** that there weren't issues, after I told them what is wrong. After phoning again they eventually came back and suggested that the problem was indeed what i told them in the first place. Ford has the worst labour fees as well as I don't know where you let your technician train because it takes them and hour and a half to replace a part that takestake me 10 mins to do myself. Ford Hatfield charges R1270 to replace a ford figo water bottle that is double the price of what the part itself costs which is ridiculous and I don't know how it takes a technician an hour andand a half to do that if even my 8 year old niece can do it it 20 mins. This is ridiculous and telling a client that you have ordered the replacement parts but when I want to buy it it's not available is ****ing me off. Your service is **** and the prices your charge on labour is even worse. Try teaching your technicians the best possible way of doing something instead of teaching them to work as long as possible to charge the maximum labour fees. Surely this isn't the type of service you would get from your competitors. I am seriously annoyed and disappointed in Ford's service and pricing in general.
