This breaks our heart but we’re working on a solution.  Unfortunately, as DEFT payments don’t allow us to see who the final bill provider is, they are not currently approved with Amex.  Rest assured, we’re working on a solution and hope to turn DEFT back on in the near future. You are still able to use a Visa or Mastercard for DEFT payments. We will let you know as soon as DEFT is available for Amex cards again.
