I bought a Sony phone for Rs 17,000 and within four months it started having software issues. Since then I have exchanged over 12 mails with their customer care and visited their store twice. At first, they said it needed a software update and now they are calling the phone dead (mentioned on the job card issued by their service centre in Lajpat Nagar, Delhi). I believe the handset is defective and should either be replaced by the company or they should give me the refund. Rajeev Narayan It seems Sony has not dealt with your complaint seriously. You may send a final notice to them, stating that the mobile should be replaced or they should refund the price you paid for the same. If they do not respond or take necessary action, you may file a formal complaint at the consumer forum.
