KWID, Renault.

I bought a brand new Renault Kwid in May 2018, the brakes make a terrible sound when I brake I took it back to the dealer and they told me its DUST, really, sounds like metal to metal, (BRAND NEW CAR) My hand brake light keeps coming on and makes a beep beep sound I then felt my brakes are soft and feels weird, however When I called Renault Silverlakes they said check brake fluid, so I did that at a garage in Mayville, and to my surprise the brake fluid was EMPTY!!!! so I have to buy a new bottle and they filled it for me..... I have had Aircon issues that it does not come on for a long time when I then realise that I am sooo hot fan on 3 and its not like aircon at all, then I must switch it off and back on sometimes it kicks in sometimes not!! then after having the CAR at Renault Silverlakes the took the wheels off to checks the brakes, they told me dust, Which is not the case at all, the sales man told me if it happens rince the brakes with water... Nice move, now the most terrible shudder on the front wheels when I drive over 100km/hour. I am not happy with this car and I feel they must settle this account with MFC and take this car back, I have had endless hassle.
