What Is a Credit Card Chargeback? Basics and Process Errors
A chargeback reverses a transaction via the card issuer, bypassing the merchant. Consumers use it for fraud, non-delivery, or defects; merchants lose funds plus fees (~$191 average, Truevo).
Process: Cardholder files → Issuer notifies merchant → Merchant responds (20-45 days) → Decision. Networks like Visa/MC/Amex set rules: Visa cardholders have 120 days; MC/Amex/Discover up to 120-540 days by issuer. Merchants respond in 20 (Amex) to 45 days (MC).
Common error: Process ignorance. Stats from Chargebacks911 show 30-60 day post-purchase filings spike denials if late.

Chargeback Time Limit Mistakes and Why Claims Get Denied
Timing kills claims. Consumers: Visa 120 days from transaction/delivery; Chase 60 days. MC/Amex/Discover: 120 days typically, up to 540. Merchants: 20-45 days to respond.
Checklist:
- Track statement date +60-120 days.
- Note issuer variances (e.g., 2025 MC digital goods compression).
- File written disputes (FTC: address changes 20 days pre-billing).
Banks deny ~55% for late filing + poor proof (PayCompass).
Consumer Mistakes During Chargebacks: What Not to Do
Consumers err by skipping refunds (contact merchant first!), vague claims, and myths like "always win" (real rate ~21% myth vs. strategy-driven wins, Chargebacks911). FTC advises: Keep receipts, notify billing errors in writing.
Checklist for Filing:
- Contact merchant first.
- Gather receipts, emails, photos.
- Use specific reason codes.
- File within limits.
