Reliance Broadband — Changing of connection

I am having a connection of relience broadband in Madinaguda location of Hyderabad we had always having issue with connectivity.later we changed our residential to Masabtank.and applied for shiftting the connection to Masabtank.i have paid two month of internet bill of more then 2000, even if i never used the net connection in the shifting transition period for one month(still i paid the one month unused bill of 1100).
While shifting from my previous residence I had asked for the uninstallation but nobody from their side turned and I had to do this myself. Again after coming here at my new residence I still have not able to use the connection due to lapses from their end. I had sent across my id prroofs 10 days back but still they have not done anything. Not even have they replied to my mail. I have sent 5 follow up mails but of no use. Nobody even bothers it seems. On a daily basis I have been calling the customer care but they say this issue of address change is with some other department and so on.. now on top of this they have generated a bill for this month also for 980 Rs. I already paid 1100 Rs o[censored]nused usage for last month.Can you please help ?
