[Resolved]  ICICI Bank — ICICI Bank unauthorised deduction MAB charges

I have two salary accounts with ICICI bank, Mohali branch.
My account no :[protected].
My mobile no: [protected]

My account has been debited by

[protected] MABchgs-Feb21+GST 483.37
[protected] MABchgs-Mar21+GST 399.99

And second account[protected]
[protected] MABchgs-Mar21+GST 3.61

Without any confirmation amount was deducted. I am having a salary account and as per my knowledge salary account has no minimum balance requirement.
I lost my job last year due to this pandemic. I don't have any job right now and I arranged this money for my personal use because i am outside and stuck here due to covide 19 situation and
it was deducted. I am very disappointed.
I didn't receive any email or regarding changing my salary account to a savings account. (If this is the case).

I emailed customer service, also live chat with them. But they didn't provide any proper solution.

I am very frustrated I am gonna close both accounts due to irrelevant charges. Please understand my situation and refund my money back in my both accounts.

Help me with it
Thanks
