"title": "Fake 'card services fraud department' harvests card number and CVV under a five-minute deadline",
"probability": 95,

"recommendation": "block",
"entity": "'Card Services fraud department'",
"red_flags": [
"1. Caller creates urgency by claiming the disputed charge becomes final and the callee liable within five minutes.",
"2. Caller asks for the full sixteen-digit card number and the three-digit security code, which a real issuer never requests on an outbound call.",
"3. The organisation is a vague front ('Card Services', 'the fraud department'); no bank or card network is ever named.",
"4. Caller refuses to give a call-back number and claims the case 'closes automatically' if the callee verifies independently.",
"5. Fear tactic: an unauthorised purchase in another city is presented as proof the card is 'compromised' before any details are checked."

"language": "en",
"tcpa_comment": "No genuine company identification, no purpose beyond the pretext, no call-back number and a refusal to let the callee verify. Not a marketing call, so opt-out rules do not apply; the conduct is fraudulent rather than merely non-compliant.",
"summary": "The caller poses as a card-issuer fraud investigator, reports a $499 purchase in Miami and pressures the callee to read out her card number and CVV within five minutes to 'block' it. The callee declines and says she will call the number on her card.",
