Purchase not going through

I’m trying to buy the Blizz essentials pack. After entering my payment information,
I have a “Please wait while we take care of some business” message.

That message has been sitting there for an hour, and the transaction isn’t going through. I mean, I tried.

Hey there!

You’ll need to go through Customer Support and not here, since this isn’t something that I can do as Heroes Quality Assurance. Hopefully they will be able to help you!

How do I reach them?

This would probably be the best place to start. Contact Support - Blizzard Support
