Elica — Auto ignition of 4 gas burner under warranty not working after multiple visits by elica technicians

I bought a Elica 4 burner gas stove 694 CT VETRO 2J (TKN CROWN DT AI SERIES)on 23rd Jan 2021. The auto ignition for one of the burners was faulty from Day 1.

After multiple visits by ill-informed technicians, who first refused to acknowledge any problem and finally ended up changing the auto ignition unit last month.

Since last week auto ignition is again not working. Have been asking to replace the entire unit as it is faulty from Day 1. However no response. Have written to Suren Pillai as well but abs no response.

Pathetic after sales service and need a permanent resolution.
