Its truly disheartening, when we pay with hard earned money placing our trust in others to deliver what was promised, and get gypped.
A friend purchased a Kent water purifier and within a month the switch as well as the solenoid valve concked off and the local office was giving him a hard time to attend to his complains, he posted on social sites and and other complaint sites and made it into a sort of a campaign, within a couple of days the Delhi headoffice called and apologized for the same and the same day the local office sent a man and got the repairs done.
I'm mentioning this cause it works with most of the time.
Hope your problem gets resolved to your satisfaction at the earliest.
