Apple double charging my purchases and refusing to refund me!!!

Anyone else experiencing Apple double charging them for purchases made with Apple Pay but not through the App Store? For example, if I pay for a game via "Link" and get charged by Link directly, why is Apple also charging me for the same purchase? They have denied refunding me several hundred dollars for money they never should have taken in the first place, and they told me to take it up with my bank. Wow, Apple, DO BETTER!!!! When I purchase anything else online with Apple Pay, I never see a charge or a receipt in my App Store for those. Please, make it make sense. Because you even did it to my Venmo and PayPal account too, yet they are refunding me for the money you deducted from my accounts with them. I have ALL THE RECEIPTS, you can't deny it and actually think you can continue to do this to people. Shame on you!!!
