Whirlpool India — Malfunction of refrigerator

Sir,
I have bought a whirlpool refrigerator on 23.8.2019 from the Central Police canteen, Calicut, Kerala. Contrary to our expectation and the good will of the company the product is not working for last 4 days. We have reported this matter to Krishna Agencies the authorized service center of whirlpool products in Calicut and a service personnel came promptly and done the service by obtaining a service charge of Rs.500. As soon as the technician left the place we have noticed again that the cooling system is not working and the complaint still persists. On enquiry it is learned that we have to replace the fan inside the system urgently.
We are just in wonder why a product from a reputed company like whirlpool is having such problem within such a short period and why the service personnel is not competent enough to resolve the problem efficiently .Kindly look in to the matter urgently and initiate action at the earliest so as to keep up dignity of the company and relieve us from the existing difficulties
with regards
Hemapalan
