Tata Docomo — No refund received

This is with regard to complaint docket number[protected]~~M13378717 filed with Tata Docomo. Ever since I bought my datacard for 3g broadband 10GB download service in Dec 2012, my datacard was never activated(forget even getting the offer I was promised). Finally, fed up after sending emails to their [protected]@docomo.com, talking to their customer service and even visiting their head office in Koramangala(Bangalore), I asked for my datacard amount back in the month of March. They refused. I even complained to their appellate multiple times who also refused. A letter has now been sent to their branch manager in Koramangala and also to their Managing Director's office in New Delhi. If I do not get a favorable reply by the end of this month, I will approach court in the month of June.
