TATA SKY DTH - Not provide servces but charge for this

Hello,

My name is Sanjit Kumar Mishra.I used tata sky since last three months.My subscription id is 1046883950.There have no power in my tata sky set top box since last friday (15/10/2010).But they are continue to deduct money from my tata sky account. For the complain very first I tried to contact their local boy Rajinder he told me there no set top box at office when In tried to contact their office the result is same.I even complain online but only a single phone call from them but no any action.And still they are continuing to deduct my balance.

I did not have idea where to go for this.

Regards
Sanjit Kumar Mishra
