I was sold a reject Polo 2019 comfortline DSG

I bought a 'new'Polo 1.0 Tsi Comfortline DSG from Bidvest Mcarthy VW Arcadia in December 2018 before reaching 1000km the car brakes failed and I was told about a software upgrade now the car has 6188 kms there is a squeaky noise coming from the front wheels and the car shakes when the it changes down gears when it comes to a stop and there is a funny clutch plate smell I never drive the car on manual or sports I believe I have been sold a reject of a car considering this was my first car.
