HDFC Bank — Debited amount without intimation and fake messages.

I opened salary account. While opening the account, bank staff told like "we can manage zero balance in salary account". But now they are detected amount for Nov, Oct and Dec. Each month they debited RS. 708/- from my account without intimation. But in message they mentioned RS. 600/-, detected amount is different, message is different amount. This time very tight situation due to COVID, but bank are detected amount like this and debited amount and sent fake details. I need my amount.
