Flipkart — Ordered POCO M2 PRO but received old mi phone form Truenet commerce Seller

I ordered a poco M2 pro but received an old mi phone form Truenet commerce. I contacted flipkart customer care they said I will receive a mail, I received the mail to attach my id proof and received phone photos and I sent them a mail. But in response they replied "Since we had requested for a few images of the product received by you and it was not shared with us within {TAT}, the return request could not be processed by the seller". I don't know what to do, pathetic experience form flipkart. The seller Truenet commerce is also bad. Trust form flipkart is gone. My replacement request is rejected twice now.
