Flipkart — Apple IPhone

Hi, I have ordered an iPhone 11 white Color 64gb variant from Flipkart on 22nd September 2022 for 30, 028₹, which was delivered on 27 September 2022.
I ordered white Color but received in purple. When I asked delivery boy, he told me to get replacement from flipkart, when I contact flipkart they say it was on open box delivery product, so no replacement, now I am confused where should I go, what should I do?
They rejected my replacement. I said ok, I am ready to keep purple Color but at least provide me the right bill, in bill it says white Color, I may warrant related issue in future (apple customer care told me)
I am sharing the sharing the screenshots of the same.
In the bill, it is written white Color, imei is right.
