Consumer Redressal

We bought an elica chimney for our kitchen on 6-4-2013. Its button for fan stopped working for which we are complaining since last 6 months in the service centre at dehradun and pune. But there is no rectification made yet. Everytime a new person comes from service centre sees the chimney and goes back aftersaying that pcb for the chimney is not available. We will correct it in 10 days when pcb will come. But it has been 6 months and no action is been taken. We are staying in a flat and thesmoke collects inside the house while cooking. I have a 5 months old baby who has developed allergy to smoke because of that and is suffering with sinusitis.
