Flipkart — Flipkart rejected my refund requests for missing items

Order ID - OD[protected]
I had placed an order for 25 items, I recieved 4 of them and I'm satisfied with those. The rest 21 of the products are missing in the 7 packages that I recieved and instead of those 21 items that I ordered, I recieved 7 completely wrong items in those 7 packages even though each package has 3 items billed in it, so totally 21 items are billed but all 21 is missing. And they've processed the refund for 6 items, the rest 6 is pending even though they say they've sent the refund and the other 9 orders have been rejected of the refund request multiple times. I kept calling customer care and they say they'll resolve this issue but then they kept rejecting the refund multiple times. I have spoken to the customer care 4 times regarding this. They also blocked one of my accounts and it's phone number. It's giving such fraudulent behaviour and I feel like I've been scammed by these people on Flipkart. The 3rd time I spoke to them, this girl told me my account has been blacklisted and she cut the call abruptly. I called the 4th time and this lady said she'll raise a concern about the refund requests and send an email, which I haven't received any yet. They're not taking this issue seriously and I want my money refunded. I hope this place can bring me my justice as a consumer complaint company.
