Bank Of Baroda — lien balance

There is a lien balance in my bank of baroda account. I can't use that money. Kindly release that amount as i don't know why they have done this. Reaching the customer service representative is also very difficult and also they don't have any proper answer.
Kindly solve this issue as i can't use my own money. It's also very confusing as it will show a different effective balance. We have to open the mobile application or net banking to know the effective available balance.
Why do you make this so confusing?
