ICICI Bank account frozen and charged 1571

My ICICI A/c 112501502711 has been frozen but the Bank has charged me Rs 1571 from one of my trading accounts with Sharekhan without any notice a few days back.

How can the Bank start charging like this and that too from a trading account without my permission?

This used to be my salaried account long time back and I have not used it ever since (about 7 years). Now all of a sudden it pulls my funds from a completely different trading platform i.e. Sharekhan.

This is complete intrusion and a violation of trust with the company. I request this to be taken up since it is not so much about the money as it is about ethics.
