Usha International — steam iron purchased in july 2017 continuously posing problems

I had purchased steam iron o[censored]sha from reliance digital on 16.07.2017. Since purchase sole plate has been changed, wire has been changed (At my cost). Today short circuit in the plug that could have resulted in an accident. Again and again requesting the dealer to change the piece but they are not listening. Did not accept this from a big name like usha. It will be great help if you interfear in this matter and solve the problem.
