Horrible service and *********** mechanic

I took my car in for repairs at Bidvest McCarthy in centurion. the car couldn't start and was towed to the dealership. the dealership quoted my warranty insurance over 100K to fix the car (Car worth less than 60k). the insurance wasn't gonna cover that amount so it became my baby. knowing that I cant pay that much to fix a car, I sent another tow truck to collect my car. found myself a mechanic who fixed the car for 3500k, I had to pay them 5000k for stripping it and pay tow truck as well.

the most disgusting thing about this whole affair is that when my mechanic had to fix the car, the following parts were missing and I had to spend more for new ones;

1. One hydraulic lifter (Paid R150) 2. Intake idling sensor (Paid 1200) 3. One exhaust lambda sensor (Paid 1100) 4. Turbo bolt (Paid 200) 5. Cambelt pulley (Paid 350) 6.Oil pump pick up (Paid 300) 7. Below surface engine cover (Still not there)

I spent an additional 3000 on parts that were not supposed to be replaced but were missing when the car came back. the car was misdiagnosed even thought I paid 5000 for the diagnosis, according to the dealership the engine (block) had to be replaced. this was proven to be incorrect as the only problem was one piston which was broken as a result of overheating and had to be replaced with not even a scratch on the engine block.

the car is now perfect, if the car was properly diagnosed my insurance would have paid for it as the amount was going to be well within my cover limit and I would not have had to incur such ridiculous costs and to make matters worse with missing parts. I have emailed the dealership several times before I bought the missing parts, even went there personally but I was not taken serious.

the painful part of this whole story is that this is the only remaining Alfa dealership around PTA and if we are treated like this where are we supposed to go as Alfa drivers? I am now selling the car at a giveaway price as I do not want to see myself at that dealership again.
