Flipkart — Product not delivered due to operational issues

I ordered Motorola edge 40 neo on 8 Oct 2023 on Flipkart. Order ID OD[protected]. Expected delivery date was 22 Oct. Even if the extraordinarily long waiting time was forgiven, the product came to the nearest hub and was out for delivery on 22 Oct itself. It is still undelivered 3 days later. Ekart tracking status is "Unsuccessful. Unable to attempt delivery due to operational issues". I don't understand what operational issues can come for a simple delivery. Multiple calls to customer care have yielded no result. They just keep extending the timeline for resolution. Pathetic service and response. I still don't know what happened to the package and where it is.
