BAD SERVICE AND A USELESS CAR

Bought a used car 12/03/2019 from this date till today I’ve been having endless problems with this car. It was dirty car sits; dent on one side of the car; car was not serviced before I took it; then the hooter stopped work. Now I don’t even know what’s wrong with the car since 12/08/2019 the car was sent to Hyundai Newcastle when it just stopped in the middle of the road I had to get a tow truck and pay for it. If u don’t call them they don’t call u back and when u get hold of them no one can tell what’s wrong with the car and when will it be fixed. Already 30 days went by the car is still at the dealership they called me Tuesday to say I must wait nog 21 days????????♀️. I’m paying for a car that I hardly use. This is really bad that such a huge well known company sell such problematic cars. U go there cause u trust the company but what you get u get trash car and service on top of it.
