fraud purchase from App Store Subscription

Hi everyone,

I recently encountered lots of fraud transactions from two games, war robots and roblox.

There's over 40 fraud transactions from those two games, and reported to Apple many times.

The things happened once I click subscription from Roblox, then got dozens of fraud transactions since then.

I've reported to Apple, they never admitted any potential security leak for storing customer's credit card numbers, and never refund the fraudent purchase.

Please advise whom whould I submitted to, Iv'e lost over $500 usd and changed three credit cards, yet still happened every time.
