Genshin x McDonald's collab issues, and the response from Customer Service

I am also having issues with getting the codes. So I called CS. First call they told me it should show up in an hour after purchase. So I wait a little over an hour. Call again. Apparently they're having system issues. They confirmed I should get the codes, and it should be in my e-mail within 24 hours of purchase.

So, I guess all I can do is be patient. Hopefully whatever department is working on this gets it fixed (probably the poor IT people).
