Can't purchase BO4

So… i’m trying to purchase Call of Duty BO4 via the battle net desktop app, when i finish to fill my payment info i still getting this message “Zounds! An internal error occurred. Try again a bit later” i have enter my info correctly, i have money on my card… i just check it!!! is there a maintenance error or what?

There aren’t any known issues at the moment with the payment options. Have you tried another browser by chance? If so and it persists, please contact the payment provider since the payment may be blocked or restricted for certain vendors or a different payment method.

Good. Don’t give any more money to Blizzard. In fact, try to get a refund for the balance of your card.
