WORST WORST WORST SERVICE EVER!!!!

I have a 2.0 L Ford Focus TDCI, 2 months ago it didn't want to start so we had it taken to McCarthy Ford The Glen,it was the cam belt that had snapped and it would take a week to repair. We ended up paying around R30 000 for the repairs and services on the car and when it was returned after 2 weeks, I was very disappointed. The car had a strange tapping sound and started smoking from the engine, I had it returned immediately. After a week with ford I went to go collect my car, the mechanic told me I should just buy another car, I wonder if he was going to give me the money for this new car?? besides there was nothing wrong with it other than the cam belt that broke that made me take it to them in the first place. The mechanic then goes on about how the car doesn't perform like it used to or like the first time they returned it, he said he didn't know why but its all he could do. I took my car and I returned it the very next morning, it felt like it had an 1.0 L engine with no turbo. I am now told I need to pay to get the Injectors replaced. I am now so Furious about taking my car to Ford, No professionalism, No knowledge and No Idea on what they are doing. Still Waiting !!!
