Amex Blocks Curve in Anti-Competitive Move
By FF Newsroom · 30 January 2019

Like thousands of other UK merchants, Curve has a valid merchant agreement to accept Amex payments into its e-wallet. However, on Tuesday evening, Amex decided to terminate this agreement and block all Amex transactions to Curve with immediate effect.
Amex has given no good or fair reason for their decision and we believe it is entirely disproportionate and discriminatory to Curve and all our (joint) customers. UK payment regulations clearly state that Curve should be allowed to access the Amex payment network on a level-playing field with every other fee-paying and legitimate merchant.
Rest assured that you can still spend the funds that you have already topped up to your existing Amex Wallets.
