Please read the following threads which might be some help for you.
So, after reading, you will realize that you can unfreeze your bank account with legal action but you can't unfreeze the lien amount which will be locked until the I.O clears you out of the case which again will result into complete loss for you.
If you don't really need that account and the funds locked are less than a lakh combined then just let it be, trying to unfreeze will cost you more and in future try not to repeat the mistakes which I mentioned in the first thread.
