TATA Indicom — False Billing - denial to rectify the same

i have been using a tata mobile since oct 2006, i had three connections one land line no. and two mobile no. under some priviledged plan offered by tata, i used all the phones till march 2008, then i realised taht even when the phones were not used much the bills generated were very high, for the enquiry i visited the raipur branch near amapara, and met Shweta Madam, whose response was highly unacceptable. prior to that i had been trying the call centre no.121where anyone who picks says sorry.. as they can not provide any help, they can only provide data reflecting in their records, later after giving application two of the phones got disconeccted(though the time taken was "remarkable")and 1 mobile no was continued. this mobile though not been used much still shows a high billing... last bill which was payable in august was of 1380, i paid the bill on line with my credit card, and called up why was the bill so high, they said madam do no. use hue hai isliye(surprise!!!) on confirming about the other no. reflecting on my bill(which belongs to mr OP sharma- PH no. 6458626) i got a complaint registered (not to mention definitely - had to call 11 times) and several different people were explained... finally i was fortunate enough to a confirmation of request no. ref no=[protected], till date it is not actioned.
today on calling up again they have given a new ref no.[protected] no one is ready to co-operate, who should be approached please suggest.
