Franch Express Courier — Courier was not delivered for more than a week

Address:

45, Manikara str, kumbakonam

My dad sent an important documents to me from kumbakonam in the date of 3rd Nov to Bangalore.
It has been more than 8 days now, till the courier was not delivered.

When I called the courier person in the number [protected], he told he will get it tomorrow on 6th nov.
When I called him yesterday, he started shouting at me saying I have to come pickup the courier.

I tried reaching the company's customer care, they never answered my calls till now.

If the company is this bad, why are they even running the service.

My important documents is in the courier and noone is responding for the same.

Kindly help me with the needful action
