Unhappy with Renault Kiger

On 26th of February my Renault kiger started complaining about the engine then I took it to the dealership on the 27th on the 28th I was told the care is fine, on Monday I too the car back to the dealership as it was complaining about the engine again, I was told they can boo my car for a check up on Monday the 9th of March, on that day I took the car to the dealership at 16:00 I was told the engine is dead it needs to be replaced, and I need to make means to get home as they will not organise transport for me mind you am pregnant I had to find a way home, they can not organise me a curtesy car because the warranty has not approved the claim of a engine in which they do not know when will that be done, if the warranty is approved I need to wait for another 5days so that they can provide me with a curtesy car, this car was bought brand new and is giving me engine problems in less than 3years of owning the vehicle, I do not advice anyone to buy this brand if you want peace of mind go with another brand
