[Resolved]  ICICI Bank — ICICI Bank ATMDEC charges

Dear Sir / madam,

I am having my saving account in ICICI bank . But few days back Rs. 29.50 was deducted from my account and when I looked into my mini statement it was described under "ATM DEC CHG" and when I tried to explore it over Internet, I found these charges are applied for when ATM of other bank declined to withdraw the money, if it doesn't have enough. So is it ethical to charge customer for this reason. Although I was having enough balance at that time.
Moreover, it is also not legal as per RBI rule.

Transaction details : 12/03/2021 ATMDEC CHG/[protected]/3072+GST

I want a proper justification
