Nexa — Sales person kept scratches on my car purposefully

Address:

560037

I took a delivery of my baleno on 7th of September 2016.
I observed there were few marks near left and right door handles.I asked salesperson.He said it will go during buffing and you can carry it next week for same.
Next week when I carried the car he denied of any marks.Then after me repeatedly telling his manager came and said bring car next week we will have a look and if required we will do a buffing.
At last when I took car next week the salesperson was very rude and he drove and took my car to PDA and to fit floor and Dickey mats.
When he brought the car he kept scratches on my front bumper.
