Flipkart — Not giving refund back

I've ordered the Cheston MS Steel Ladder from flipkart on 16th july 2023 and received it on 21st july 2023 due to the poor quality I wanted to return it but the return option is not showing although it has the 7 days return policy, in the order panel it is showing order is cancelled by the buyer but I've received the order.I've also connected with support team of flipkart several times also sent them 4-5 times email regarding the problem but the issue didnt resolved yet.I'm attaching some proofs that I've received the order.
