Flipkart - Flipkart is not ready to accept the product for Return

I had ordered * Smartwatches, one was Noise colourfit Pro * and Other was Gionee GSW * and both costed me ****, but when the packages were delivered, The Noise watch had a dead micropixel, and the Gionee smart watch has some in-box contents missing and also it was really inaccurate and wasn’t able to connect to my phone. So, I tried to return both the products to Flipkart but it’s not ready to accept the order back, the customer support always gives the reason that the seller has told that the product is ineligible for refund and I have tried filing the refund request multiple times, but Flipkart isn’t ready to proceed after a call I get from technician and then they cancel the refund request after *-* days, and in some days they’ll close the return window and tell that I can’t return the products.
