Ekart Logistics — Not delivering the product which is out for delivery

Ordered Nothing phone 2 on Oct 13 2023, during Big Billion Days. The delivery date was on 14th Oct 2023. It has reached the nearest hub which is 10 min away from my home. Still the item was not out for delivery till 20th Oct. Raised complaint and called Flipkart multiple times, but no help at all. They were not at all concerned about the customers. On 20th Oct the product was out for delivery at 1.14pm, but later around 2.30 pm they marked "Unsuccessful Unable to attempt delivery due to operational issues". I tried to call delivery guy multiple times but not answering the phone. Such a pathetic experience from Flipkart and EKart. I am like spending my time, energy and money contacting them every single day. Still no help
