[Resolved]  ICICI Bank — Monthly average balance charges made by bank on zero account

I have zero balance salary account in icici bank, i lost job in pandemic and salary could not credit in my salary account.
Icici bank without giving me intimation converted my zero balance a/c to regular account and deducted Rs.869.44 from my account as on 26 april 2021.
When i contact to bank they replied as it is converted to regular account, you have to maintain rs.10000 mab in your account and accordingly charges are deducted.
My complaint is that bank did not inform me about conversion of such account and erroneously debited such mab charges.

Yours faithfully
