I purchased a Kutchina premium brio kitchen chimney in January 22. The first flaw- The dealer (Sangeeta Agencies, Rourkela, Odisha)has still not entered the invoice number in the warranty card after several reminders. I was entitled to three free services, they came twice and each time the technician insisted on tips. The third time, two technicians came one after another and insisted that I provide the kerosene they needed for cleaning. When I emailed the customer care they insisted that I provide the fuel. Nowhere in the warranty card it has been mentioned that the customer should provide the fuel. I should say they are cheats and their services are horrible. Never buy a Kutchina kitchen chimney.
