Sony India — Fault in SmartPhone

Address:

Chennai, Tamil Nadu

Service Complaint : I bought a Sony C3 mobile before 2 months. I haven't completely used it for one day. But before that itself, mobile got some problem. Sim card tray isn't working fine, so sim card is not detectable. I gave it for service before 2 months, still it is in service center and they are not ready to repair and give my phone back. Can anyone take this into serious action and get it settled. Phone is lying there for the past 2 months, but still they didn't repair it. Service Center is in Tambaram - Chennai (TN). Moreover, I bought this mobile for 26K, but now the price has reduced to 20K. If I had bought this by now, I would have saved 6K. Thanks
