Flipkart - Payment stucked with Flipkart but they deny

I have paid **** rupees to Flipkart on * March **** for the order of Boat Earphones . I made the payment through G Pay and the amount got transferred to Flipkart but Flipkart didn't place the order . I have contacted them many times in past ** days but they just keep on postponing the refund to ** hrs and so on . Now they say that the payment has not been received by them so they could not refund it nor they can place order . But the Google pay receipt and the bank details show that the payment has been successfully received by Flipkart. Bank says the payment is with Flipkart and they can't do anything about it ...
