Terrible service and damage vehicle

I have purchased my Toyota Fortuner and took delivery of the vehicle on the 3rd of January 2019. On inspection of the vehicle, I identified paintwork scratches and damages to the vehicle. The sales person confirmed to me that I can take delivery and they will book the vehicle for a polishing to remove the scratches. The vehicle was taken a month after my complaint for polishing and was returned to me in a worse manor with more damages. I have immediately contact the salesperson and informed him and sent him pictures and to date I am still awaiting for a resolution. I have been made promises and but none has materialized. It has now been 9 months and I am still waiting.
