Understanding Debit Card Charge Disputes and Your Rights
Debit card disputes fall into two categories: unauthorized fraud (e.g., stolen card) and merchant errors (e.g., wrong amount, non-delivery). FTC guidelines mandate banks investigate within 10 days, provisionally crediting funds. CFPB oversees complaints, requiring evidence like statements and affidavits.
In 2025, FTC reported $12.5 billion in debit fraud--a 15% rise. You're protected if you report promptly: banks must zero liability for fraud reported before unauthorized use.
