Flipkart — Missing item in grocery order

I have placed a grocery order in Flipkart which got delivered on 11th September 2023. But 5 items are missing in that order. I informed the same to delivery person he told that those products are not packed while doing packaging and asked me to place return request. But I am unable to place return request since the product is not delivered to me. With the help of customer care service, two times placed return request to get refund amount for those 5 products. But without even contacting me, the return request has been rejected by Flipkart. Again today I placed return request to get refund amount. Please do the needful.
