Nokia 7 Plus
My Question or Issue
I made my one-time payment (1 month) using Momo.
The transaction in Momo was successful (my Momo balance was subtracted) but when I was redirected to live.adyen.com/hpp/completeMomo.shtml, it said
Invalid Request Unfortunately we were unable to process this request
The page also showed a 'Previous' link but it did not do anything.
