Disappointed customer by renault paarl

Im runita and i just bought a 2018 model renault kwid last week friday 06/04/18 and i only drove it on sunday after it has been deliver on the above day mentioned,sunday the car switched of 3times i ddnt think much of it and monday morning on my way to work it did the same thing about3-4times i thought its me leaving the clutch to fast maybe as the pedals is stiff and new but yesterday tuesday it did the exact same thing in the morning,yesterday evening when i finished work i got in the car and the car did not want to start at all and its dark im stranded now and the last taxi has gone i phone my dealer on his cell he told me i should leave the car there and phone roadside assistance in the morning not worried how i get home, anyway this morning i phone roadside assistance and they came and fetch the car i went with the driver try also to switch the car on and nothing happened,this is a 4day old car renault telling me i need my brand new car's battery maybe charged , i mean really a 4day old car u dnt even get this nonsense from a second hand dealer, i spike to several people which gave me the run around and no one could even assist me to take me to the dealer where i bought the car i had to call a friend from work to come all the way to take me to renault paarl where i bought the vehicle where the manager flat out told me he will not accept the car back because i refuse to pay for a faulty car, whether its just a flaat battery i dnt care a new car is not suppose to have a flat battery after 4 days, and the speedometer was jumping from 14km to 12.3 on sunday and monday it was jumping to 104.7km i mean really cleary they trying to ripp me off and want to make everyone aware of this and their service upto now has been appalling to say the least, my money is good but now i cant get a new car because clearibg this is a manufacture fault of which i refuse to pay for because the boss at renault ddnt even have the decency to call us in his office we had to have this conversation in the road in public. I am going to the paper now with this and i dont want to make this a race issue but they way they treated me a white person was not gonna get this treatment at all as i am working in the customer service industry. Hope those who read this will come forward because we are the consumer and we have rights and im well in my rights because my car i bought was suppose to be a brand new no failts period.
