Nsdl E-Governance Infrastructure — account statement not receiving

Address:

borivali west,Mumbai 400092, Mumbai City, Maharashtra

I purchased 4 non convertiable debentures from varius companies in august/sept/oct 2019.
Even after writing and calling nsdl numbers there is no reply since 15 days
There is toll free number of nsdl but they are giving big bhashan, insted of resolving my problems. Sometimes nobody picks the phone,
Even after writing 3 letters in 15 days there is no reply.
Today one person called me and asking for rupees 70 to lodge a complaint.
I am asking for quarterly printed statements which is free.
