If you have a charge on your corporate card that you feel is fraudulent, you need to call the number on the back of your corporate card to report/dispute it.
SAP Concur is not a company card issuer, so we cannot provide any assistance with reporting or disputing charges. The best way to think of this type of situation is to handle it like you would your personal credit card if you have fraudulent charge.
Only the card issuer can reverse the charge and get the issue cleared up.
