Amazon India — OnePlus 10 pro Mobile is not delivered. It's been more than a 15 days

Address:

Hyderabad

I ordered mobile on July 24th. The delivery date is Aug 4th. Delivery agent had not delivered the product that day saying it's been already 8:45 hence cannot be delivered. But the next or till today Aug 8th the product is not delivered even though after so many calls to customer support. Customer support is not useful. Not a single person is taking responsible for the product delivery. They were saying it will be delivered in few minutes or by EOD. But still I didn't received my mobile.
