Delhivery — Product shown delivered but not not received yet

From Assam, Guwahati. I have ordered a product from Meeso on 28.11.2021 .it was a prepaid parcel. it was assigned to delivery courier with AWB No.[protected]. My address was my official address. the product was out for delivery on 05.12.2021 i.e Sunday. As office was closed on sunday the delivery executive partner Name- Wahid who was assigned the delivery called me . I told him that office is closed today you can delivered it tom me tomorrow. he told me that i will show the product delivered and hand it over to you tomorrow. I gave him the OTP, he showed the product delivered. but till today i.e. 15.12.2021(Wednesday) he did not hand over the product to me. I called him many times .Every time he shows many excuses such as the parcel is kept in office, it is kept in godown, could not find it etc.

Kindly help me out.
