Havells India — ventilair exhaust fan/fan falls off from the rectangular frame...asked to pay in spite of guarantee

Address:

Thane, Maharashtra, 400604

Had raised a complaint on your customer care: HF231106. Please refer attached photos: I had purchased the Ventilair exhaust fan in February 2018. After 4 months the internal fan dropped off the outer rectangular frame. Technician Nitin Dubey came to check the issue. He said the fault is with some plastic part inside. The fan got obstructed by this part and eventually came off. But since the faulty part is plastic it does not come under guarantee, so I'll have to pay 400/- extra and he'll replace the whole set. I complained to customer care about the extra cost and the 2 years guarantee which was promised. But he says that breakage of the fan is not covered, only technical issues are covered. I tried to reason with him that my issue is technical as well because it seems to be a manufacturing defect or bad quality part issue but he is implying I am to be blamed since it worked for 4 months without issue.
It's been only 4 months and I've paid around 2, 500/- for an exhaust fan instead of average 1000/- only because I believed Havells is a quality brand. I want to know why I should pay extra money in just 4 months (given 2 years guarantee) for no fault of mine, having already paid a pricey amount for an exhaust fan from Havells.

Resolution: To replace the whole set free of cost.

Kindly respond and resolve.

Regards.
