Lightinthebox — refunding not done

Dwar sir.
I have purchased mobile from lightinthebox website. They ship the parcel with extra amount charged on the name of costome tax. They didnt imform me about tax at the time of purchase.
I refuse to accept delivery as they charged me extra amount. I have return back the parcel. It is more than 1 month of return the parcel but i havent receive my refund. Even lightinthebox costomer care msg me that they will not refund me full amount. They will deduct their charge around rs.1700 from the amount and remaining amount they will refund. I told him to lz refund my remaining amount. Bt it is more than 1 month i didnt receive my refund and didnt recieve any information about refund. I got cheated by lightinthebox website. Dont by from lightinthebox website. Completely fraud website.
