Faber India — 4 burner gas stove

Had bought a faber 4 burner gas stove before Diwali. It had a defect in its stand and took almost 2 weeks after repeated complaints to get sorted out. Then God knows what the technician did during installation, the gas extinguishes once you turn the knob to sim. I am unable to use the gas on sim which is causing a great problem while cooking. Plus its a fire hazard because many times out of habit we sim the gas and gas keeps coming out and after some time we realise that the gas has extinguished. It's quite dangerous. It seems a part has to be replaced to rectify this problem. Even after repeated complaints for more than a month the part has not been replaced. Absolutely horrible customer service. I am very fed up. So please think twice before buying one of their products.
