I purchased a DVD with great expection of good quality product and service from onida,with in a year the product has shown its true quality, and i called the local service center to lodge a complaint and found the staff at the reception and Ms Keerthana who is an incharge speak very arrogantly and dint know a bit of courtesy. They were crude in their conversation,Although i had a valid warrenty card with date and retailer's seal, they insisted on purchase bill. No where in the warranty card , its mentioned that the bill also has to be produced.they were trying to nullyfy the warranty on some pretex or the orther.
