Ekart Logistics — Cancelled my order on Flipkart without my consent

I ordered 301ltr fridge from flipkart and it is a open box delivery. They showed me opening the box... The fridge has dent on it and i asked for replacement instead they cancelled my order. I bought that fridge in sale with approx 9k discount and now because of your lazy executive fault, my order got cancelled and wrote a lie about the reason of cancellation on flipkart page.
