India Post — Item Onhold Insufficient Address

My package ET[protected]IN is stuck at Vimanapura SO with the reason - "insufficient address", despite the package having a complete address and correct details like name, flat number, apartment name, landmark, area pincode and mobile number.

I wasn't contacted even once on the provided mobile number if there was any trouble with the delivery attempt.

And my other package ET[protected]IN with the exact same address details was delivered successfully 2 weeks back without any such issues.
