If your bank still refuses to defreeze your account you can tell them the following:

Mohd Rizwan Ansari vs. State of Uttarakhand & Others. Writ Petition (M/S) No. 699 of 2021

In paragraphs 10 & 11 the Hon'ble Uttarakhand High Court stated:

"10. In view of the aforesaid legal position, this Court has no hesitation in holding that the direction issued by the Investigating Officer under Section 91 of Cr.P.C. to the Branch Managers to freeze the Bank Accounts of the petitioner, is not sustainable in the eyes of law.

11. In such view of the matter,  the Banks are not bound to comply with such direction as regards freezing of Saving Bank Accounts of the petitioner. "

The bank cannot go against the HC's decision. Tell them you will be sending them a show-cause notice soon and will drag them to court and sue for damages for violating your personal liberty under Article 21 of the constitution.
