Yes, Wells Fargo disputes generally work for unauthorized transactions and billing errors, providing a structured process to reverse charges. The bank investigates claims, often providing temporary credit within 10 business days, and typically resolves unauthorized debit card transactions if reported promptly. However, disputes are not guaranteed and must be for valid reasons, such as fraud or undelivered goods, not just buyer's remorse.
