Consumer Redressal

I have been using the Reliance NetConnect data card for the last two years. Since Sep\'13 the broadband connection has not been working. Inspite of various complaints , there has been just one phone call to confirm the complaint, but no technician was sent to correct the matter. I discontinued the service after waiting for two months. In spite of this the RELIANCE NETCONNECT keeps sending the monthly bill and keeps calling for dues. Last month I received a Notice from one Mr. Shadab Peerzade, claiming to represent Reliance Broadband services, saying they would drag me to court over non-payment of dues. Kindly guide me on this bullying Tactics Reliance Netconnect is resorting to. Still there is no effort on their side to correct the matter.
