Delhivery — Failed Delivery attempt for[protected] . No Response on Ticket 51457431

Tracking Details for id:[protected] have changed overnight. Whereas on 09th Nov 2022, it showed estimated delivery time as 10th Nov 2022 10:30 to 18:00 IST. Today on 10th Nov 2022 07:45 IST it is showing estimated delivery time as 11th Nov 2022 IST. What is the cause of this delay? How many times will delivery be pushed back without any evidence of attempted delivery / communication from the delivery person? I have no response on support ticket 51457431. No response after posting my complaint on Facebook. No Further response on facebook messenger. And nothing beyond automated responses on email.
