Customs duty details not informed to me in prior to clearance. Now they are asking to pay the amount more than the product I ordered as customs, as they done this I lost the option of returning the product where I would get the money in return excluding the return shipping costs, now they are asking me to pay customs duty other wise order will be abandoned, as they collect my KYC documents they are liable to inform me about the charges of the customs duties
