What to do next
Go to the brand's site by typing the address yourself, or use a bookmark you saved before — never the link from the message. If you already clicked through and entered anything, act on it now:
- Your bank or card issuerAlready paid or shared card details? Call the number on your card and ask to dispute the charge or freeze the card — do this first, before anything else here.
- FTC — reportfraud.ftc.gov The US Federal Trade Commission takes consumer fraud reports here. Outside the US, your country's consumer-protection agency is the equivalent.
- Google Safe Browsing Report a phishing or malware page so Chrome, Firefox, and Safari can warn the next person who visits it.
