Unauthorized Transfers and Fraud
Scams like phishing or account takeovers trigger unauthorized EFTs. You have a 60-day Reg E window to dispute--banks must investigate within 10 days and provisionally credit funds. Example: Jane lost $5K to a scam; her dispute letter reversed it in 8 days.
Wrong Account, Failed, or Delayed Transfers
Sent to the wrong account? Demand reversal. Failed/refused transfers (e.g., recipient rejected) or delays qualify for refunds. Mini case: John disputed a delayed SWIFT transfer, securing $2K compensation after 45 days.
Fee and Error Disputes
Challenge excessive fees or bank errors. Domestic ACH resolves in 10 days; international SWIFT takes 30-90 days.
