Indian Overseas Bank — Unwanted Bank charges

Address:

Chikkabidarakallu, Bangalore

I am using IOB bank from past 4 years from last three months they are simply deducting the money in the name of bank charges. When I saw the passbook it was written as CHARGES-MIN BAL ONC/01-10 -
2019/[protected]
CHARGES-MIN BAL ONC/01-01 -
2020/[protected] why are they deducting money in 2023, If I had not maintained min balance in 2019 or 2020 they should have cut those charges then itself. My account was completely active and I had money even at that time I used to have atleast 5k to 10k in my bank account. This is completely unfair.
