Kaff Appliances India — Chimney

Address:	500087

I have purchased kitchen chimney (Model: canberra) from kaff appliances store in kondapur, hyderabad in october last year for my new house.
From 2nd day itself, the chimney was not opening and we lodged a complaint. Kaff technician (Mr vinay) attended to the complaint and in his attempt to open up the chimney, he broke the glass cover. He said the company will replace it and make the appliance good. We have subsequent recorded telephone conversation, both with the technician as well as the area manager, mr. Bhaskar konne.
Despite repeated complaints, the chimney continues to be locked up and not opening and is not functional. Kaff is not responding. Can you please help?
