1. Call Your Bank or Card Issuer Fraud Line Immediately
Minute 0 to 15 (Verified 1 Nov 2026)Dial the official phone number on the back of your debit/credit card or inside your verified banking app (never call a phone number sent in an SMS or email). Tell the operator a fraudulent transaction occurred, ask them to freeze compromised cards/accounts, and ask whether a bank-to-bank recall request or card dispute applies. Banks cannot guarantee fund recovery, especially for authorised push transfers or crypto, so speed is critical.
