ADYEN ERROR?

I have been buying the monthly card for 9 daily Ancient Scriptures all of the month of November, then come December and my charge is rejected with a mysterious error of ADYEN ERROR! see your webmaster. Usually my payment goes through Facebook Meta Pay but no sign of transaction rejection there nor at my bank. Support for this game doesn't exist - they no help at all. Well I guess I am forced to be a "Play For Free Player" because they are making no effort to fix this problem. Anyone out there having the same problem?
