Address:

Gas is leaking from burners when stove is still under warranty. Flame is coming out of enclosure and extending it to hands. Has raised several complaints but service centers did not respond and Once service attendant did visit but he took only 5 minutes to reach conclusion. This is serious negligence with consumer safety. Need help to escalate the same
