Elica — Worst customer care

Case id: 1487348
One of the worst customer care..My gas hob, 2 burners are not working properly, and burner needs to be replaced. I have raised the issue in the month of September 2020. They said, burners will be replaced in free of cost as Brass burner has life time warranty. But they said due to covid burner is not available in stock, so it will come in month of October, followed up in October they said it will come in November, again in November they said, it will come in december. In December they said they found alternate as it is not available. but for that I have to pay the money. I have asked when it is under warranty and if you are not able to provide then it should be free for alternate option. After that, they said that burner is not brass, it is black enamel brass (which doesn't cover warranty). I have sent the picture of burner. To my surprise they are saying, I have rubbed the burner and removed the enamel to make it brass burner. Not sure if it is possible.
