Never buy costly products..!! My money is stucked.!!

I ordered quick charger with AA size battery for Rs.1050 but they sent me normal 12hr charger. i mailed them prob. and they called me and said to return the item next day, and it will take 7days to dispatch new item. I did , and now in status its showing: “seller received” in red font. And its been 10days still showing same message. I mailed them so many times regarding new product, and they are not replying on FB, mail, twitter etc.

Worst customer care!! Before this i ordered cheap things like glass, pen drive, earphone, tshirt. All were OK. But now i’m never going to buy costly items from tradus. they are neither replacing the item nor returning my money. I’ve lost Rs.1050

I dont know what to do now. If anybody can hep me to get my money, plzzz PM me.
