Fake supply of sandhi sudha plus oil

I had ordered sandhi sudha plus oil for joint pain relief dated 02/06/2012 for an amount of rs.3450,which was delivered on 012. But instead of sandhi sudha plus they delivered shandi sukh nimoil(please pay attention on the names). Also the packing of the bottle(sandhi sudha) which was shown on the television is different from what I received(shandi sukh nimoil). Already the oil is so expensive and top of it they have cheated me.I had ordered this for my father and mother as they are suffering from joint pains,and these cheaters have cheated me big time. Please help me,I want my money back (or) the original sandhi sudha plus oil. Thanks & regards.
