NTT Volkswagen East London does not give a fakh, after sales sucks

After sales sucks, a car that is less than 3 months had a problem with the window and the electric winder fell inside the door. I'm being told I'm the one who broke it I must pay an extra amount to fix it njani??? So they are the only ones with sense I'm the crazy one🤬🤬🤬🤬
