DHL Express India — huge customs duty on dhl shipment

Address:

560035

I had purchased a clothing item of value 116usd from US which is around 8250 INR. DHL has just sent me a message asking for a customs duty or 5824 INR which is around 70% of the value of the item. I've faced this issue only with DHL. What can I do now?
This is not the first time this is happening.. but atleast the last time it was in the range of 20-30%. But 70 % is ridiculous. Is this a nexus between the customs an d DHL to loot individual customers. and when i called the customer care, i was told this happens a lot in case of individual customers.
