Don't care attitude.

I took my vehicle for an Oil service, which they quoted me on. I requested some clips to be replaced as well, which they quoted me as well. They then called to say the vehicle is due for a brake fluid service, which I agreed upon. When I collected the vehicle, I had to sign an invoice for some software upgrade, which I wasn't told about and didn't agree upon. When driving home, I realized that the vehicle is now smoking heavily, which wasn't the case when booking it in. It then came to light that the software upgrade that I didn't agree upon, caused the smoking. After speaking to the service department, I was told that there is nothing they can do from their side and that I need to take it back to the company who did the software upgrade for me previously. Problem is, I had to take time of work to take the car from Kempton Park to Pretoria, leave it there for 3 - 4 days, get a lift back and repeat it again to collect the car. And on top of it all, it's costing me close to R5000.00 to get it fixed. Communication could have avoided this. Worst of all, no assistance offered.
