Blue Dart Express — courier undelivered and no response after messaging time slot

Address:

Pune, Maharashtra, 411057

No response on message for delivery slot and no way to get the courier collected. There should be some way to have get our courier and the courier tries to deliver on his convenient time and usually on weekdays, so should someone sit back leave his work to collect his courier and plan his weekdays and you don't even have a way to get in touch and schedule a different delivery slot except message but they don't even respond
