Order Processing

I am trying to order from Chuwi directly, instead of through Amazon. The checkout says they accept American Express but the payment servicer is not accepting that card type. Can I get some help processing this order as that is the only type of card our corporate office has authorized our company to use.

I do not know the payment operations, please write to service@chuwi.com where they will tell you where to go or what system to use. Thank you so much
