L&t Infrastructure Finance Company Ltd Complaints & Reviews

I invested on 20 L&T Infra Bonds for Rs.20, 000 vide application acknowledgment # 42819344 dtd 23/12/2011 and was credited in my Demat account of HDFC Securities (NSDL). It has matured for more than a year but no payment has been credited to my account yet. I have never received any physical communication from the company in last 11 years. I also didn't bother since it is in my Demat account. Please help me in getting the matured amount to my linked account to my Demat account. Or inform me the right procedure to claim.
