I brought a RO purifier. After installation it didn't worked and the service engineer approved of replacement which was immediately conveyed to their maintenance service. I have been waiting for their response for quiet sometime while continuously contacting, asking them for replacement without any result. Then I contacted the dealer for help, since the dealer was our own cooperative stores, (Atomic Energy Employee Cooperative Stores- Kalpakkam) they assured all kind of help, they refused to sell any product from Whirlpool. This way I got the replacement, that too with a lower end product.
Don't buy anything from Whirlpool
