renault - poor and pathetic after sales service

I bought a Renault kwid climber in November 2018. Within hours of taking delivery of the vehicle I had a problem with the brakes on the vehicle. I took it back the next day and was informed that the noise will eventually go away. The noise became worse and I took the vehicle back to Renault. They supposedly repaired the noise but it still persisted after taking the vehicle. I took it back at least 3 more times before I had to eventually tell them what the fault was. Within a month I have experienced many other faults with the same vehicle and have been taking the vehicle back to have it repaired. This is unacceptable especially when the vehicle was bought brand new. The manager at Renault is not helpful and the after sales service is pathetic as I was pushed from pills to post and no body is prepared to assist. I want the deal to be cancelled on the vehicle but the manager states that once the contract is signed the deal cannot be cancelled and that if the car has faults and defects it needs to be repaired. He even stated that Renaults policy is not to assist customers with courtesy vehicles when the vehicle is being repaired. The said manager selects who to give a courtesy vehicle to. I have begged the manager to assist me in this matter and his only reply is that he cannot do anything to help me. The after sales service is of a poor and pathetic nature where nobody is prepared to assist customers. I have since done 870km with the vehicle and have had numerous problems with this vehicle. I am not the only person who has had problems with these vehicles. I was at the branch to lay a complaint when another customer brought their vehicle in complaining about defects on the vehicle and another customer also walked in and returned their vehicle. This is so disappointing and one would never expect to have so many faults on a brand new vehicle and a customer even has to beg to be assisted and still have no joy. My vehicle is at Renault for repairs for a week now and they have not even started with the vehicle. I will personally never buy another vehicle or even deal with another Renault dealer. I would also like to advise potential customers to be weary when dealing with Renault.
