Philips HD4929 Induction Cook Top

My order id is Order ID: OD30908003548. Flipkart delivered this induction on 16th Sep-13. And it stopped working within a week time. Power suddenly goes off frequently and also display E7 error. No use of writing mails and calls to Flipkart’s worst support service. They informed that they won’t replace their defective product because their GEPL seller don’t follow 30 days replacement policy. Flipkart is cheating customers in the name of their seller’s policy.
Kindly take action on this kind of online cheaters.
