Renault kwid's are faulty!!!

Why was i sold a faulty car??? I bought a BRAND NEW Renault kwid 5 Novemeber 2017 and on 18 December 2017 had to take it in as the gears were not changing smoothly. I took it in and i was told the gear box is faulty and has to be changed! The dealership had the car for 2 weeks and i was told to collect it as the gearbox was changed. After reading several articles online about the kwid, Renault blames the drivers about their driving s****s. If the gearbox was in it's proper, competent functioning form it would still not be faulty in a space of 6 weeks. 22 August 2019, I saw a warning light flashing and I immediately booked it in for 27 August 2019, and now i was told the Accelerator pedal had to be changed. What nonsense is this? I bought a car brand new car for reliability and avoiding constant back and forth to dealerships. I am utterly disgusted, i absolutely hate that car. And more so highly disappointed at why these cars have not been recalled for our safety.
