Dear dishank_24 ,
Kindly post the Item number you have purchased.
No genuine Seller would ask for additional charges.
If its a mistake on Seller's part then you may file INR dispute.
If you are at fault then talk to your Seller and ask him to refund the money.
Always try to first resolve the matter, amicably.
Its a very small deal and it should not spoil the relations between you two.
