When a seller takes your money and the goods never show or arrive broken, a written refund demand creates leverage and a record.
State what you ordered, what you paid, what went wrong (no delivery or defective), and a refund deadline. Attach the order, receipt, and photos.
You can dispute the charge with your card issuer (chargeback), and deceptive sellers can face New York consumer-protection complaints (Attorney General; NYC DCWP). Use these alongside the letter.
Both can run in parallel. A chargeback is fast for card payments; the demand letter preserves your claim and supports a lawsuit if needed.
Usually 10 to 14 days. Keep it firm and dated.
The self-help letter and a chargeback still work. Attorney services here are New York only.
