Put to: The supplier’s authorized decision-maker, with a US consumer-law specialist for legal interpretation.

Why buyers should ask: CFPB guidance distinguishes billing-error procedures from disputes involving defective goods. Its billing-error guidance specifies written notice within 60 calendar days after the charge appeared on the statement and cautions that defective-goods complaints may follow a different process. A card payment should therefore not be presented as guaranteed recovery for an overseas fit dispute. (consumerfinance.gov)

Draft answer framing: Ask for the contracting business’s identity, exact specification, payment milestones, cancellation treatment, delay process and remedies for nonconformity. Establish which document controls if the quotation, website and messages differ.

Ask the card issuer about the relevant process before paying and promptly if a problem arises. Do not assume the supplier’s remake discussions extend any issuer deadline.

Press for: A readable order agreement and written clarification of disputed terms. Proposed staged payments must be agreed with the supplier, not imposed after ordering.
