Tikona — Delay in deactivation of tikona internet connection

I got tikona broadband connection on 24/11/2012 by making payment of rs.1800 (My user Id is [protected]).For few days days connection was working fine but later it started to give trouble that I was always getting the message as "limited or no connectivity". Regarding this I started to complain to tikona technical support and was being asked to do some exercises like switching off & switching on power adapter,removing cable & connecting back.But still problem was persisting.Finally I requested for deactivation of broadband, but they told they will solve the problem by sending a technical person to my home. In fact he came my home and he tried to to get good signal. But he DID not get and he told me that my connection have poor signal and he told he will inform the the same to tikona for deactivation.But they(tikona) were not bothered for deactivation, they just kept on postponing telling that they will solve it. I strictly requested for deactivation on 24/12/12 with complaint no [protected].But I don't know why the connection is not yet deactivated and I received a call from tikona on 08/01/2012 for payment of bill of rs.456.53 for the period 22/11/2012 to 15/12/2012.I asked the status of my connection he told it is active and I am surprised to why these people are acting like this. After so many requests for deactivation of connection, they have not yet deactivated it and I have not used the broadband after I requested for deactivation,moreover they have generated one more bill of rs.1398.11 for the period of 15/12/12 to 14/01/13. So I request you to help me in this regard.Following are the complaint nos.
