Kaff Appliances India — Chimney duct pipe installation

I bought a chimney on Dec 30 and the technician came and drilled two holes and placed the Chimney without placing the scuff plate and duct pipe. He told that he would get an aluminum pipe(next day) and it would cost 1500/-. He charged me 570/- for placing the chimney on the wall without connecting the duct pipe. I bought a duct pipe and called him the next day and he told that he would charge extra Rs.300 to fit it. I called his manager and he said that the whole world pays this and you can complain to anyone.

These people are looting money. When i called customer care about this, they don't have much knowledge on the charges of duct pipe and gave the contact of the same person who was threatening me. What a pathetic customer care of KAFF and the installation guys are looting money.
