Bank Of Baroda — i am complaining about lien amount

Address: Bangalore, Karnataka, 560068

Sir,
I am a customer of bob, iam facing a issue with this bank, from past few months in my account rs.700 is shown and i cant able to use. When i speak to the customer care they did not satisfy me with their answer, from more than a half year they blocked this amount without any reason.
I request you to remove this lien amount and credit back to my account so that i can use my own balance.
Bank is not allowed to block the amount like this without reason from more than half year.
