Thanks for posting, @mccorke!
Would you be able to provide a bit more information on your question? I am sure the community would be happy to provide insights and a bit more context would help them do so. Are you simply wanting a contact number or do you have a question involving your AMEX and SAP Concur products?
I would agree that more information is needed. The main lines for Amex Travel Help are:
1-312-980-7807 (outside the US)
But, I have a feeling your company has company-specific numbers that you may need.
