St Courier — Courier service failed to deliver and asking us to claim from office.

Address:

Neyveli

I sent the product from Neyveli to Andhra Pradesh via ST Couriers on April 26, 2021. But they failed to deliver the product. And its today May 15. For past 1 week they said they will check and tell and today they are saying claim from the ST courier main branch by raising the complaint. How can a person so be irresponsible and making customers not satisfying, I want to take legal action against this courier service.
