Biovea India — Additional Custom Charges on Order No. 43128907

I had ordered hair oil of Order No. 43128907. After a significant delay in delivery of order, the post office delivering my order has called me to tell that I have to may customs duty of Rs. 1994 on my product for it to be delivered to me. I had paid total Rs. 2174 (product cost of Rs. 1814 + shipping cost of Rs. 360 i.e Total Rs. 2174) during the time of order. I don't understand why I have pay such huge additional customs duty of Rs. 1994.

Please look into this as soon as possible else I will have to resort to taking this to consumer court.
