Consumer Redressal

I took a tikona internet connection on 25th November 2012. The connectivity and service provided by Tikona was not good right from the start. Finally in March, I disconnected the service and cleared all the dues. I received a confirmation mail from tikona mentioning that my pending dues are 0 Rs. A Tikona personnel collected all the equipments from my house somewhere near May/June. Recently, I received a call from an advocate informing that a case has been filed against me and a warrant would be issued. I was informed that I need to clear the dues. On contacting the customer care, the representatives say that the modem was not returned and hence a due amount of 1500. I have returned the modem. Please help me against this harassment.
