Process Timeline:
- Notify bank within 2 days (immediate freeze).
- File formal dispute (60 days ACH, 120 days wires).
- Provisional credit (10 days USA).
- Investigation (up to 90 days).
- Final ruling--appeal via CFPB/FCA if denied.

ACH vs Wire Transfer Disputes: Key Differences
| Feature | ACH | Wire Transfer |
|---|---|---|
| Reversibility | High (95% with proof) | Low (20% direct; 40% via CFPB) |
| Timeline | 60 days | 120 days (USA); conditional |
| Cost | Free | $25-50 fees |
| Pros | Easy provisional credit | Faster initial send |
| Cons | Slower settlement | Often "final" per bank |
| Success Rate | 70-80% | 10-40% |
Wires aren't always irreversible--2026 CFPB rules allow reversals for proven fraud.
