Koryo — kirti steam iron

I have purchased steam iron from big bazar in pattom, trivandrum, kerala on 25sept, 18 and complained for water leakage on 5th october. It was returned on 20th october assuring that it is rectified. Had to return it again on 25oct as water was leaking. From that day it has not been returned despite repeated requests. The salesman at koryo complaint counter also not attending properly.
