The 4 Golden Rules: What Authentic Financial Institutions Will NEVER Ask
No legitimate customer service agent or automated phone prompt will ever contact you asking for your two-factor SMS OTP or push notification token.
Card issuers will never ask for your full 16-digit account number, 3-digit CVV security code, or ATM PIN on a call they initiated.
Never install AnyDesk, TeamViewer, or UltraViewer at the request of anyone claiming to assist with portal login errors.
Fraudsters frequently claim accounts are "locked" and demand prepaid gift cards or crypto transfers to clear holds. Issuers never operate this way.
Lost, Stolen, or Compromised Account: 4-Step Emergency Action Plan
Immediate In-App Card Lock
Open your verified mobile banking application, navigate to Card Controls or Security, and instantly toggle "Freeze Card" or "Lock Card" to prevent unauthorized physical and digital transactions.

Do NOT trust phone numbers from unsolicited SMS messages or search ads. Always dial the exact customer support or fraud hotline printed on the physical back of your card.
