A person's father, with a dormant ICICI bank account, was visited by bank officials claiming a wrong fund transfer occurred. The officials demanded a signed Aadhaar card to rectify the issue, threatening an FIR if not provided. The father requested written confirmation of the transfer and an acknowledgement for the Aadhaar, which the bank refused. Advice is sought on how to proceed, including contacting superior bank officers or the Banking Ombudsman.
