India Post — Incorrect delivery

I recently ordered aadhar pvc card, and it was dispatched through Speed Post. The airway bill number is UC[protected]IN. As per the tracking portal of speed post, it shows that the item is already delivered on 13/05/2022. However, I didn't receive it at my address, I was present the whole time at my home. Like really, what's this behaviour? And moreover, the post office's number/email isn't working, so there's no way to contact them other than to physically go. This is downright fraud.
