Hyundai needs to double check their engines

PURCHASED A CAR AT HYUNDAI PINETOWN ABOUT A YEAR A GO, BEEN TAKING THE CAR IN FOR SERVICE AS REQUIRED.I RECENTLY HAD A PROBLEM WHERE I WAS DRIVING IN THE EARLY HOURS OF THE MORNING ON THE 21/01/2019 AND THE HEAT GAGE WENT DOWN, I REALIZED THAT I NEEDED TO GET TO THE NEAREST GARAGE TO FILL IN WATER, WHEN THAT WAS DONE I DROVE OFF AND ALL WAS BACK TO NORMAL, I STOPPED AND THE ROBOT AND I WHEN I ATTEMPTED DRIVING OFF, THE VEHICLE SWITCHED OFF, I REALIZED THAT THE VEHICLE NEEDED MORE WATER WHICH WAS ARRANGED, WE POURED THAT WATER BUT IT SEEMED AS THOUGH ALL THE WATER WAS LEAKING SOMEWHERE, SPOKE TO MY SALES PERSON WHO ADVICE THAT I TAKE THE CAR TO NEAREST HYUNDAI, WHICH IS HYUNDAI 26-27 CATO STREET, DURBAN 4001.

The vehicle is still at the dealership, they informed me that the vehicle was going through an assessment, i then explained to them that my job depend on my car since I'm a sales rep and requested if they could at least provide me with a courtesy car in man time and they will contact me once the vehicle once that was done, it took almost a week to come back to me and i was informed that all courtesy cars are leased out, Ive been using public transport since and this has affected my sales performance at work, to the extent that even my manager has contacted them.

They came back to me and informed me that they cant fix my car, cause this was caused by water damage, they imp**** that i drove my car into water, i then informed them that there hasn't been that much of rain for me to drive through water and i wont drive into water cause i know of the damages it causes to a car.I told them that the only water i used on the car, was the one poured by the patrol station attendant and the one that was filled when the water broke down and i kept leaking and would stay in the water bottle/radiator.

i was told that i will have to get a new engine, i will be given a discount for my engine that will be ordered from Korea and it will take 21 working days, to me that seemed like a win situation to them because they were benefiting from diagnosing my car with a water damage, which i disagree doing.When i told them that my car over heated i was told that that was impossible cause it was still new and this showed that they were not aware or didn't know that diagnosis of my car, cause that is exactly what happened, it over heated and that radiator and water was leaking the radiator.

I need my car repaired urgently, my job is at stake and im using public transport to this very day, kindly assist.
