ICICI Bank — Amount deducted without informing us

Address:

Prakasam, Andhra Pradesh, 523157

I am the a/c holder of icici bank from last 2 years
Now they have charged 573.85 under this category dcardfee 8174mar17-feb18st74.85
I am not aware what type of charges are these.
They never informed me regarding these charges either by email or by letter.
Who has given right to icici bank to deduct the money without informing us.
Because we kept the money in bank that give right to bank that they can do anything whatever they want.

There should be some formal process for doing all these things. I want my money to be credited in my a/c which they have deducted from my a/c.
