ICICI Bank — Deduct 706.82 as dcard fee without my consent

Address:

ICICI Bank Ltd. - New Delhi - Ajmal Shah Road Branch 16/6 WEA, Karol Bagh New Delhi.

I am having A/c of ICICI Bank from last many years, today I checked the transaction detail in icici bank app and I noticed that they have deduct Rupees 706.82 dated 30th Aug, 2021 under (DCARDFEE) category.
I am not aware what type of charges are these and 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 my concent or informing me. This is wrong practise and we kept our hard earned money in Bank with trust but who 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 credited bank in my a/c which they have deducted from my account.
