Pureit / Hindustan Unilever — Breakage of the outer covering of the product

I had purchased Pureit copper purifier three years back. Few days back I could notice leakage in it and the very next day the apparatus which was wall mount just broke and about to fall down. I raised the complaint, the technician visited and was told that the outer covering was developing crack in it and that was the reason for the leakage and falling of the apparatus. I enquired what was the reason for the breakdown i was not given any information from the company side. They told me to pay entire amount for the outer covering and get it replaced and they told me the replaced new part also does not have any warranty and can break any time.
This is how the grievance of customer is resolved in this company. There is no value given to customer.
