DTC — airtel live charge

my no is [protected], its on my father id (Rajbir singh).
i used gprs 499 plan from last 06 of july 08. without my information airtel charge me 1155 rs for using airtel live, but in my notes i never used airtel live from my mobile. so why airtel added 1155 in my account.tell me how it can be possible that i m using both paid services. ( i am student thats why i try to save my money just because of that i activated 499 gprs plan.)
so many time i am dail 121 or 12118 for help but many time yours agent give me wrong information, when ever i am complaint they said sorry for that. is it sorry the solution ?
so plz take care of the case.
