Aweful aftersale customer service

I bought a brand new Hyundai grand i10 in 2018. It's not yet 3 years old and only has 50 000km on the clock. Firstly the aircon packed up in the first year which they fixed. Then the 2nd year my battery gave up the ghost which they replaced and now my timing chain ontop of it. And to top it off they don't keep spare timing chains because timing chains should never break. So it had to be ordered from Korea which took 21 days. We only have the 1 car. My husband was retrenched in March thru covid lockdown. He only got a new job now and I'm told sorry you won't get your car back till its fixed and oh sorry we don't give Courtisy cars either. So we sat without transport for 3 weeks. They don't give a ****.... They were very eager to sell me a new car and put me further into debt than to try help us out. So my 75 year old mother had to get up at 4am everyday and take my husband to work and take my child to school and fetch again in the evening. She has to drive through wallecdene everyday at her age. This stress made her sick.... Last year my car roof was scratched while my car was in for a service. The workshop manager came to my house to look and said he will contact me to have it buffed out. That was in February and he never got back to me again or rep**** to any emails... That's the standard of service they give. I will never ever buy another Hyundai. I will be trading it in on a different make car. The attitude of the big manager of Hyundai brackenfell is so arrogant, and head office says it is what it is.... I'm furious..... I finally got my car back not even 1 apology. Just sign here and here's your keys. They don't even walk with to show a customer where the car is. Terrible......
