I cant buy Modern Warfare

this website is quite frankly terrible. constant errors loading pages, links dont work, and its really frustrating. I’ve been trying to buy modern warfare and on the checkout page it asks for my last name, but the last name box is not working. ive tried gifting it to myself but that doesn’t work either. you guys really need to fix this stuff. Also, the launcher has this same issue as the website.

I have also had this issue with the last name bugged out. I’m using blizzard balance, but the issue is still there. Have you found any solution?
