UPS India — Parcel not delivered

Hi,

My parcel from Singapore has not been delivered yet to my address in Bangalore, India. It has been more than a month now. I have been following up with them for more than 1000 times. They failed file it with the customs and delayed and delayed and was suggesting me to return it back to the shipper without any valid reason.

And when I insisted to know the reason they were giving me every excuse and exorbidant customs duty and penalty (because they delayed) and as asking me to return. But when I insisted, finally the customs duty worked out to be way less than what they quoted and the penalty also way less but the penalty is still around 40K INR which is purely due to their mistake.

Now they are refusing to deliver unless I pay the penalty.

Is there any legal course of action that I can take?

Any suggestions or advice is more than welcome.

Thanks,
