HDFC Bank — Money hold without any prior information from a salary account

This is the second time this is occurring.
Rupees 1, 468 has been kept hold from my salary hdfc account for no reasons
First thing is that the account is a salary account thus there is no need for a minimum amount per month.
Last month the same issue happened and an officer from the bank called and informed that he'll revert it but nothing has happened.
I need an answer from the bank side.
It states some Mirevenue hold gefu
Please help
