[Resolved]  HDFC Bank — Trading login_id / password not received

I had applied for Trading cum Demat a/c with HDFC Bank at St. Mary's branch at Secunderabad thru personal banker Mr. Venkat.
I have received the demat a/c bot not yet the trading a/c login_id & password due to which I was not able to sell my shares timely in the stock market. Moreover I am also not able to buy any shares from Market. I do not know what to do with this demat a/c when I am unable to buy or sell shares.
I contacted HDFC Bank for help thru their website which evoked no response.
Contacting Mr. Venkat at HDFC Bank is also of no help since he is asking me to directly deal with HDFC at Mumbai.
This is the type of customer service being provided by HDFC Bank when you request them to open a Trading a/c.
