Unable to buy AirPods online with an international card

I found out the reason - this particular bank is having issues with processing payments on MasterCard type of cards - as simple as that. I still have no idea why no error was shown and who should be responsible for showing - Apple or the bank.

So the question is closed.

I couldn’t find a way to reach directly (except calling them which isn’t an option for me) - first link offers to choose a device I’m having issues with (my devices are okay) or find a repair store. Second link isn’t helpful either - I have only one card in USD (no option to change payment method for me - PayPal is accepted registered for the US only) and it works for other purchases within US (open a new card isn’t a good solution). Besides there were no activities within the card from the store, I see no ‘declined’ messages, no activities within the bank details meaning it wasn’t even reached to take a payment, so it looks like declined by Apple without even a message to me on what’s going on.

So right away I see no reason for the card not to work, except for something hidden…

My order was to a local US address - not international shipment.

And I'm a tourist visiting - they will reject my foreign card? That doesn't make sense. Even if that's so - why there was no error message saying that the card won't work for the purchase.

Besides, I used to pay this way before, so this is something new.
