HDFC Bank Securities — unauthorized opening of demat account and transfer of funds

Address: East Khasi Hills, Meghalaya, 793018

Demat account was opened without my authorization and signature in march 16 and i was not aware of the entire happenings till much later. It was obviously done with information being leaked by some bank officials. I was never provided a client list or welcome kit ever. On being asked the standard reply was 'this can happen' but my request to close the account is still on process.
There has been some deduction of charges due to low balance due to unauthorized transactions.

Kindly provide the client list immediately so that i can transfer the securities to some other demat account and revert the charges deducted. I want to close all acoounts with hdfs henceforth.
