Dissapointment and angry at vw barons Bellville

I bought a polo tsi 2018 tredline from them it was 58000km range ...when I got home I saw they gave me a vehicle with a big deep scratch at the back I reported n they took it to fix it,2 days later I switched the air-conditioned is not working when I took it back they said the wire is damaged they fixed ,and also the mats were damages and they sew them ...my vehicle is not even a year old yet window button is looses windows don't want to roll down and the gears are just locking I took it back they say they will only fix the buttons the because I ddnt take the warranty but when I asked them when I was signing the contract they said everything is included that's why I even added scratch and dent....i am so angry and disappointed at the same time because they sold to me a s**** vehicle
