Sony India — sony bravia tv problem

I have registered my sony bravia tv compliant on last week friday through sony toll free customer care. On that day simran from customer care attended and asked me to try factory reset option but nothing got fixed again i called to sony and registered[protected] my compliant one guy from customer care informed that i will get call from their service center. Till now i did not received any call from the service center. Today[protected] registered my compliant again rajesh from the customer care informed their service center person will contact me. Still no call i received from them. I have warranty period. Are you trying to pull the warranty date and make it as chargeable service.
