Ajio — My order is marked as delivered but it is not delivered

On dec 13, 2021 I placed an order. Unfortunately I placed it to my university address and couldn't check until it is out for delivery but I graduated from that University. I tried contacting delivery team but failed. I don't know to whom they delivered it and as it is a exchange order, only 15 rs needs to pay for that product. On the same day itself I informed to expressbess ( courier partner) regarding this issue.

How can they deliver prepaid order to someone without asking any proof. Kindly, help me.

Ajio raised a complaint and closed it stating it is resolved. I don't even know what they resolved. It's been one month and still they are giving irrelevant responses.
