HDFC Bank — Amount Hold and debit without Statement

Good Evening
I am a customer of HDFC Bank Ltd, I had open my account as a Salary account in Feb.2018, In January.2021 I was operating my Mobile banking found my amount is on hold, I was tried to track my statement but the hold amount was not there, the same situation was running till May.2021, I contacted the Customer Care Department and the Local Bank Manager they don't have any idea about this hold amount transaction.
I wrote an email to the customer care with the seniors on March.23.2021 but no one replied to me after that I wrote on my social media Twitter account about this scenario they "Hi Danis, this is to inform you that currently there are NIL hold funds in your account. Secondly, Funds get on hold by the bank in customer's account when there are no credit balance in the account for recovering the charges. Further when account is in credit balance"

for your reference twitter conversation is attached.
