Glen — Glen Chimney improper installation

Address:

Chennai, Tamil Nadu, 600007

I had bought a Glenn chimney at Saravana Stores chennai. For installation chakra services chennai representative came and instructed me to get my loft cut by plumber and wall too to be holed. I did that after which same technician came. He used a rusted screw to fix the end cover of chimney flexible duct. kept the gap between wall and flexible duct without filling. Also not fix the fused light. From January even after repeated email complaint to Glenn head office nothing done so far
