Bad service

I bought my brand new 2021 mahindra kuv 100 k6+ from mahindra west rand( i had no problems ) I took it for its firts service(3000 km) i got the car back and they told me everything was fine. When i opened the hood, i noticed that the engine cover was missing. I called and asked if the engine cover was still in the workshop, they told me no. I then talked to clinton and he said that he wil find out for me. I send a picture to petro who sold the car to me( she never replied back) the car went for its 10000 km service, and i asked them again what is going to happen about my engine cover. They told me again they wil find out( but nothing happend).its almost 3 month later, i called them again today to ask about my cover. The one said that he told the other one, but the other one does not know about anything. She told me that alin wil call me. So i resieved the phone call from alin, and he tells me that the car never came out with a engine cover. So i googled the model and saw that ist got the cover on. I also called mahindra in brits to confirm that my model has the cover and he said yes it comes stock sandard with the engine cover on. So i called alin back, ( his story changed)Then he tried to tel me that they discontinued the engin cover on my model and that is why mine does not have it on. But i know i received a new car with a engine cover on. PATHETIC i want answers?
