Consumer Redressal

I had changed my tata docomo datacard plan to unlimited usage plan of Rs 900apprx. . Accordingly had submitted all the documents at the Tata Docomo outlet in New Panvel.On asking when this plan will get activated , the executive out their gave us a date . From then on we started using net thinking the unlimited plan has got activated. One fine day , I got a msg of Rs 4500/- bill usage under this number . We ourselves went to the outlet to enquire. Their we came to know that the concerned executive didnt forward my requestand she was not ready to accept. We told them that we are willing to pay the plan rental amt which was Rs 900 apprx. But the Tata Docomo people are insisting on me paying the bill amt of 4500 apprx . why should I pay the excess amt with no fault of mine . Since then they are harassing me and even sending people home . kindly look into the matter.
