Hyundia *****ed my 63 year old mother & **** about fixing her car while it is still under warranty

Good day

I am writing this complaint on behalf of my 63 year old mother in the Eastern Cape. As I am writing this, she is stuck on the road, for the second time in 2 weeks, with the same problem in her car. On 31st May she was stuck between Fort Beaufort and Healdtown. She then had to call a tow truck, which charged her R800 to get the car to Superquick in Fort Beaufort. 3rd June, road assistance towed the car to Hyndai in East London. I was then left with no car for 9 days. After all that inconvinience, she had to pay about R3700 as the dealership claimed that they had found a diesel in her car. She felt this was very strange and didnt understand how it could have been possible. She then felt that before she could dispute this, she needed to get some evidence from the petrol stations. Engen in King Williams town where she put in petrol, confirmed with a slip and showed her a video footage that they put in petrol, NOT DIESEL. BP in Fort Beaufort gave her slip and wrote a letter that they also put in petrol in her car; NOT DIESEL!!! She was planning on going back to Hyundai in East London next week Tuesday the 17th June where she was *****ed, with all the evidence. How absurd it is with all this lie!!! Today 14th June, she is stuck now between Fort Beaufort and Healdtown again, the car just won't drive. She's called Road assistance and she's been asked to wait for a tow truck that is about 120km from her. Imagine!!! An old lady stuck alone on the road, in the middle of nowhere where there is so much unsafe in our country. She's been waiting for an hour now for assistance. Can you imagine if this was in the middle of the night!!! We want a money back, and compensation of all these costs she had to pay including petrol costs, inconvenience, phone costs. This car is still under warranty, bought brand new on 5 June 2018. This is unacceptable! Bad service, lies, and inefficiency!!! We want answers now from Hyundai, her cell number is ********** .
