HDFC Bank Securities — loss due to negligence of prm

Address: 711101

I am a preferred customer of hdfc bank and i have been provided prm for trading named mr narendra from howrah branch. As i have instruct him to buy hpc for intraday at 11.5a. M. He confirmed me that trade has been executed at11.29 a. M. But i found they traded at 3. Pm when i called him for update. Previously
I called him at 1. P. M. To confirm whether share bought or not but they neither pick my call nor call back. Due to his negligence i have suffered loss. Now my concern is who will bear the loss?? As i had asked him again n agin wherher he will track the share n trade at said price or not? After his confirmation i stop tracking that stock. So i request you to please take quick action against him and give my suffered money back.
