ICICI Bank — Multiple instance of NACH_AD debit from my account (pre dated debit)

My ICICI Bank account number is[protected]

Multiple debits of 590 rs has been happening on this account.

Today is 4th of June and already 3 separate deductions of 590 has happened today and the date shows 5th June. (how are you already deducting money before the actual due date without any information?!)

I use this account for my SIP investment and ICICI has been exploiting me my deducting money wihout any warning or information.

As per guidelines the bank is permitted to do this deduction only once a month. Why has this been happeneing all this while?

Kindly look into it at the earliest or I will haev to take the legal route
