Consumer Redressal

we have been getting cheated for for more than 2 years by the representative of INTECK ELECTRNICS, BANGALORE (Nirup).He never gave any receipt of the service and replacement he did for the KENT RO unit. The SMPS unit that he replaced just 3 months back went bad today and another representative came and said that it needed replacement again. He said the warranty is 6 months but when I told him that it was replaced just 3 months back, his manager (Jigar Patel) said that the warranty is only 2 months!!! The worst part is that the representative who visited us today, Lakshmipathi, threatened me and was all out to hit me when I raised the concern. We believe that we have been cheated not just today but several times in the past by Nirup as we have spent thousands of rupees in replacement of parts. I want to file a case against INTECK ELECTRONICS, Bangalore and Managing Director, Kent Water Purifiers for the financial loss and mental suffering we have gone through today and from last 2 years
