EA won't accept any purchase methods

I have been trying to purchase two expansion packs for the sims 4 on mac but every time I try to pay I get the message that this payment method isn't available at the moment or that they can't verify it's me.

I tried apple pay, credit card and paypal (even a friend's klarna), tried to purchase via the app and a browser - I also used another browser but nothing seems to work.
I've never had any issues with purchasing anything online so I'm sure the problem is not my side.
