Moving s****

I bought my car Kiger 4 months ago and from the words go it was bad.

The wires were visible underneath the stearing wheel and the tired wheel cap were not tired and I told the sales rep she promised to fix the tyre which it never happened and with the wires o was ignored.

Complained about touching oil (yellowish) every corner of the car and still got ignored. 2 months the line there is a funny sound from the windows even when they are closed and still got ignored,

Now the car water is licking and the car is not even 6 months oil. The water is licking while the water is about to get finished.

Kindly advise on what must I do because there should be a warranty for cars less than 6 months.
