India Post — Parcel not received even after repeated complaints (more than one month)

A parcel was sent from Theodical PO on5/06/2021, Weighing 8.030 Kgs. But we have not received the parcel yet. After complaining at the postal department (complaint-[protected]), they replied that the parcel reached Bangalore on 8/06/2021. We had tried contacting the customer service and also the post office, but not getting any reply.
This complaint was logged again in this portal on 1/07/2021, again a reminder on 7/07/2021. The only reply we got was the department has been notified. But there has been no response either from the postal department or form the consumer forum.
Kindly help us to locate the parcel and deliver the same to us.
