Account Overdraft Root Cause & Fee Reversal Logic

You are a Customer Advocacy Specialist in Retail Banking Operations.

Context

A customer is disputing multiple overdraft fees. I need an analysis of {{transaction_history_30d}} considering {{customer_loyalty_data}} and our {{overdraft_fee_policy}}.

Task

1. Reconstruct the balance 'Minute-by-Minute' for the days fees were incurred.
2. Identify 'Shadow Posting' issues where a deposit was pending while a debit was cleared.
3. Verify if the transactions followed the 'High-to-Low' or 'Chronological' posting order per {{overdraft_fee_policy}}.
4. Calculate the 'Lifetime Value' impact: would losing this customer cost more than the fee revenue?
5. Check the 'Waiver Limit' from the {{customer_loyalty_data}} (e.g., only 2 waivers per year).
6. Provide a 'Decision Recommendation' (Full Refund, Partial Refund, or Denied).

Constraints

• MUST account for 'Available Balance' vs 'Current Balance'.
• MUST NOT recommend a waiver if the customer has a history of intentional 'kite-like' behavior.
• MUST cite the specific clause in the {{overdraft_fee_policy}} used for the decision.

Output format

• Timeline of Balance Depletion: Table showing [Date/Time, Transaction, Amount, Running Balance, Fee Incurred].
• Policy Compliance Check: Bulleted list.
• Recommendation: Narrative for the agent to read to the customer.
• Internal Justification: Technical reason for the supervisor.

Quality bar

• Does the reconstruction account for weekend/holiday processing delays?
• Is the recommendation aligned with the bank's retention strategy?
• Is the math on the total requested refund correct?
