Card charges show on statements with OFFERROLE in the line — for example OFFERROLE PRIORITY, or SOURCEHIRE*OFFERROLE, depending on how the card was charged. Most unrecognised charges are a Priority Review purchase made by someone in the household, or with a work card.
Send a change request (/help/change-request, "I don't recognize this charge") with the receipt number if you have it and your e-mail. When the receipt and e-mail match, we show you exactly what the charge was for — the role, the amount and the date — and a person looks into it within two business days, refunding a charge that wasn't authorised.
If you believe your card was stolen, tell your bank too.
Send a change request: billing mistakes our records prove are refunded automatically, and a person answers the rest within two business days.
