India Post — Item not delivered till today

On 2/09/2021 I sent an item (consignment number ED[protected]IN) from laxmi Nagar post office (delhi) to be delivered to hailakandi (assam). It reached AIR AP TMO on 7/09/2021. Today is 13/07/2021 and it shows no progress. It's 11 days already.
Please look into the matter and act accordingly. It is an important item that I have parceled. It's very disappointing that speed post is not being speedy at all.
