What is respect and what is disrespect is not known in your issue. When you have borrowed something, you have to repay as per terms and conditions and can not impose your own terms and conditions on bank, unless they agreed to your terms in writing.
If you wanted to go for legal action against bank, seek your pleasure and get strictures in return complicating the issue further. The fundamental thing is a litigant must approach the bank with clean hands.
Bank has every right to exercise their right of general lien, but the only condition is that they have to give such intimation before appropriating, and keep that fund in credit till certain days as stated in their notice.
Bank's enjoy the right of general lien from inception, and this right was never challenged or agreed unconstitutional in any judgment so far.
