Union Bank ATM Transaction Complaint Guide - Summary
Union Bank ATM Transaction Complaint Guide PDF is a one-page independent guide based on Union Bank of India’s 2026-27 grievance policy and online portal instructions. It is not a bank-issued claim form.
The English guide lists the transaction details to include, such as date, amount, ATM location, transaction ID or retrieval reference, and the issue. Add an account statement, ATM receipt or relevant screenshots as proof. Never share a PIN, password or OTP in a complaint.
To file online, use the Union Bank online grievance portal and choose Add Ticket. Keep the ticket number to track updates; the bank says it sends an acknowledgement by SMS or email. Complaints can also be submitted at a branch. Check the Union Bank grievance-redressal page for its current channels and escalation details.
The bank’s policy says customers may approach the Banking Ombudsman if the complaint remains unresolved after 30 days.
