Elica — High Installation charges

After buying 41000 Rs chimney and gas stove, they can't even provide a duct . Usually whenever u buy any electronic product for eg. AC the company usually states that after a certain metre you will have to pay for the extra metre of wire. While buying elica they said us that after 5ft u will have to pay for extra duct. But while installation they told us that no u need to pay 1500 for the whole duct. This didn't even include the installation price. Which was 550Rs. The installation people was not even on time, they were 4hrs late. Such a big company and so bad services
