UNHAPPY CUSTOMER

I took my car to strijdom park Hyundai on the 5th May 2026 with no problems at all, the only issue was the fact that it was due for 90000 kms service. Sharp, during the day they tell me that my wipers need replacement (I already knew about that) I was quoted R350 for them but I declined. In the afternoon I fetched the car, then on my way home I feel that the car is not the same anymore. It was shaking at when I brake then suddenly "an emoji" like helicopter in orange came up. I knew what it meant but I couldn't go back to the dealer as it was raining and they were probably about to close. In the morning around 9 (the 6th May 2026) I went to the dealer only to be told that I need to replace ignition cables (shocked) because why wasn't I told about this yesterday when I was being told about my wipers? Was it because there was actually no issues with my car?? So I get told that I have to pay R3600 for those cables.. hmm are those cables not less than R500 when you buy them? I understand that the business has to make profit but you can't be making 200% profit, is that even ethical? Anyway now my car is shaking with the helicopter emoji on the dash. Thanks Hyundai
