Tv return request cancelled

I purchased a TV from Flipkart, which was delivered to me on 13 October in a damaged condition. The damage was identified during installation on 16 October, and I immediately raised a return request with supporting photographs. My first return request was approved on 20 October after successful uninstallation of the TV, but it was cancelled on 22 October. I raised a second return request, which was approved on 26 October after successful uninstallation, but this was also cancelled on 29 October, with Flipkart citing the 7-day return policy. My original request was raised on 16 October, well within the return period, so this cancellation was not justified. I then raised a third return request, which was approved on 4 November, with pickup scheduled to be completed by 16 November. Despite repeated approvals and cancellations, the damaged TV has still not been picked up and I have not received my refund. I request Flipkart to immediately arrange pickup of the damaged TV, process a full refund without further delay, and take appropriate action to prevent such repeated cancellations and harassment of customers.
