Consumer Redressal

I had purchased a brand new SONY C3 on the 21st from Reliance Trends. Also bought a new Micro SIM Card for the same on the 23rd, Wednesday. Inserted the brand new sim card to find out that the tray got stuck in the slot. For immediate attention, I went to the customer service center of SONY for a check up. The entire phone was dismantled in front of me and then the mother board was taken inside to remove the SIM. When the representative came out, he showed me a damaged and scratched SIM card. He used PLUCKER to remove the sim card from the tray and damaged the phone. To repair, I am being asked to pay 8000 for a new mother board, while I have not even used the phone for a minute. The damage is caused at the service center. SONY has refused to repair the phone or replace it and is instead blaming me for wrong placement of the card, while the representative verified correctly placed SIM when he removed it. Request you to kindly help a harassed customer.
