HDFC Bank — EMI TRN without notice

Address: Hyderabad, Madenaguda branch

Since I have not paid the loan during the COVID situation HDFC Bank had deducted the overdue amount on top of that they have deducted EMI TRN component. I am worried about these deductions how the bank can deduct the amount from my account without my permission. they need to inform me before deducting any amount from my account. May be bank have a feeling that my account is their pocket that they can take it when ever they like.
