Homeshop18 — amount charged in the name of prize money

I have received one message from homeshop18 that i have won tata safari worth 1280000 in the lucky draw for buying product from homeshop18 and to claim the prize they have taken rs.8600 plus rs 5000 from me in the bank a/c of aditya singh (Sbi adb pandua a/c no.6 [protected]) but after taking the amount they have stopped responding me.
They have cheated me.
