ICICI Bank — icici bank deduct my money

I am the a/c holder of icici bank from last many years,
Now they have charged 588 rs under this category dcardfee1198may20-apr21+gst
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. Same happend in last 5 months back again its happen.

Please refund my money.. I am very poor and this time i have no money for my food...
