Sir,
I had applied 11Shares and 54 CCPS Tatasteel rights issue in Dec2007 on plain application along with HDFC Demand draft of Rs 3300+Rs 5400/-. I had sent this to Ms Intime Share Registry Ltd, c-13, Pannalal Silk millscompound, Bhandup Mumbai-79 by registered post.I followed it up with 4-5 letters, however, I have not received a single letter reply till date from this reputed company. I filed the complaint with SEBI and intimated this to company. Please tell me what should I do next?
