Purchase (from APPLE.COM) refund

Hello!

I've got an issue regarding wrong charging from APPLE STORE side for my purchases made at apple.com. I have bought iPad + magic keyboard + pencil and was charges more than I was supposed to. I wrote (replied) to email from your_order_US@orders.apple.com (when they confirmed my order) about this but never got an answer. In my letter I reported a problem and attached my credit card screenshot with wrong billing from iTunes.com

maybe someone knows what do I do now? is there only one way to call on their support Line (Im from Kazakhstan) or I could write another email to another address?

Thank you in advance.
