Tata Docomo — Wrong activation of scheme

Address:

Mumbai City, Maharashtra

I am having tata docomo postpaid service. Few days back some sales person called up and ask me to convert my prepaid to postpaid by giving me some good special plan. So I gave a positive response and activated postpaid service. But after activation I came to know that the scheme plan was totally different from the plan which they had shown me. Now after activation no response is given from the tata customer care and that sales person team. They are acting like careless people and shifting each others responsibility to someone else.
Kindly look into the matter and solve my problem as soon as possible.
