I keep getting an error when trying to buy the Premium Season Pass

I only started playing in la liga tots so I only just got to 500k cos as a showcase player I ofc don't want to spend money on this game. I tried buying last seasons pass about a week ago cos I was max level and tried every day until it expired and have tried in the past 2 days for the new season too and keep getting this same message every time and a different error message on web app. This is so confusing and there is no info, fix or even acknowledgement from ea and u guys here seem to be the only people on the Internet with this same problem. I really hope someone can find a fix or ea can sort it out at their end. Can u pls lmk if u find anything out ty.
