Disappointed by Toyota Mainlyn Service

I bought a car at Toyota Manlyn end january ,within two weeks i reported that the batterie is giving me problems i needed to jump started the car now and then i called Oupa who was assisting me and informed him,he said i can bring it back to change it to my suprise they never change it they said they have tested it its working fine,a two month down the line batterie gave me a problem got stuck even if we jump start the batterie the car could not started only to find out that the batterie is finished flat. I called Toyota to inform them that the batterie gave me problem since the car is under warrant and batterie is one year warranty can they give me a new batterie they told me that its out of warranty i asked how so they say it bought in 2018 so they replace it for me.

So my question was i only bought the car in them 2022-01_28 and never disclose to me that the batterie life spam is over .they sold it like that within 3 month i had to buy myself a new batterie because toyota mainlyn treated me unfairly and o wrote them email demanding further explanation but they never even bother to respond
