ICICI Bank — Amount of Rs. 29.50 INR has debited under ATMDEC CHG category

Address: Madheenaguda, Hyderabad

I have Salary account ending with 8852 in ICICI bank and had enough money min 30k in my account and i got a transaction mentioned that Rs 29.50 were debited under ATMDEC CHG category.
when i googled it refers to the charges applicable when there is no enough money in your bank and you have tried to withdraw some amount. but it wasn't the case of trying to withdraw the amount with no amount in place.

Why these kind of transactions happening in ICIC bank? I wanted my hard earned money back
