UC27: Automated Credit Card Dispute Resolution

The Problem

Credit card disputes (chargebacks, claim requests) are high-volume and high-friction. Customer submits dispute via web/mobile; bank analyst must verify transaction details, retrieve merchant response, apply policy parameters, determine if refund is warranted. Current process: 3-5 business days per dispute; analysts handle 20-40 disputes per day. Routine disputes (clearly unauthorized, duplicate charge, merchant error) represent 80-90% of volume but require same time investment as complex cases. First-call resolution rate: 30-40% (many require follow-up). Cost per dispute: $25-50 in labor. Customer satisfaction: 55-65% (slow resolution, lack of transparency).

What the Agent Does

Receives dispute submission: customer narrative, transaction ID, amount, claimed issue (unauthorized, duplicate, not received, different amount, etc.)
Retrieves transaction history: full transaction details, prior transactions with merchant, payment method used
Applies policy parameters: rules for each dispute type (e.g., "Unauthorized transaction = refund if reported within 120 days AND no PIN used")
Generates merchant inquiry: requests merchant response (proof of delivery, authorization, customer communication)
Applies evidence from merchant response: applies policy to determine if refund warranted
Resolves routine disputes autonomously: generates refund decision, initiation, customer notification
Routes complex disputes to human analyst: cases with conflicting evidence, policy exceptions, high amounts
Tracks resolution: documents decision rationale, customer communication, refund status
Reduces processing time from 3-5 days to <24 hours for routine disputes

Data Requirements

Data Sources:

Card Processing System (Visa, Mastercard, Amex networks) , Transaction details, transaction history, merchant data
Account Management System (Core banking system) , Customer profile, payment methods, account history
Dispute Management System (Temenos, Fiserv, internal) , Dispute submissions, dispute status, customer communication
Merchant Database (card network master files) , Merchant info, merchant disputes, chargeback history per merchant
Policy Rules Database (PolicyTech, or internal rules engine) , Dispute resolution policy, rules by dispute type, refund decision logic
Chargeback Rules (Visa, Mastercard, Amex specifications) , Network rules for chargeback liability, timeline, evidence requirements
Customer Communication Templates (email, SMS) , Customer notification templates by dispute resolution type

Data Classification:

Public: Card network rules (Visa, Mastercard published specs)
Internal Structured: Transaction data, account data, dispute submissions, dispute policy, merchant data
Internal Unstructured: Customer dispute narratives, merchant communication
External Third-Party: Card network data (Visa, Mastercard, Amex), merchant responses
Sensitive/Regulated: Transaction data (card details masked), dispute details, customer financial information

Data Quality Requirements:

Transaction data accuracy: 100% (must match card network records). Transaction data timeliness: T+1 (posted within 24 hours). Dispute submission completeness: 90%+ of disputes have customer narrative and transaction ID. Policy rule accuracy: 100% (disputes must be resolved per bank policy). Merchant response data: collected within 10 days of merchant inquiry per card network rules.

Integration Complexity: Medium , Requires integration with card processing networks (Visa, Mastercard, Amex APIs). Integration with core banking for customer/account data. Dispute management system integration. Policy rules engine (may be built-in or external tool). Merchant inquiry and response workflow. Customer notification capability (email, SMS). Evidence retrieval from multiple sources requires coordinated data access.

Why It Scores Well

Dispute volume is high (100-1000+ per month for large issuer). Routine cases (80-90%) follow clear policy rules. Customer value is high: faster resolution, 24-hour turnaround improves NPS. Cost savings: reduce analyst workload from 20-40 disputes/day to exception handling only (5-10 complex cases/day). Fallback is straightforward: analyst reviews and overrides agent decision. External audience creates reputational risk if handled poorly, but clear privacy and security guardrails (card network compliance). Regulatory compliance is straightforward: follow Reg Z chargeback rules, card network rules. Political risk is low (customer-favorable dispute resolution is standard practice).

Regulatory Alignment

Regulation Z (Truth in Lending): Agent supports compliant chargeback dispute resolution timelines
Visa/Mastercard/Amex Rules: Agent enforces network chargeback rules and timelines
FCRA (Fair Credit Reporting Act): Agent avoids credit reporting impact for legitimate disputes
PCI-DSS (Payment Card Industry): Agent handles card data securely and complies with network security standards
