Sandbox/Wallet/Apple Pay hacker

So this is a long shot. My apple device has been hacked. In March, my credit card, which is in apple pay, started to get used, until May. It was used for thousands of dollars. In July i discovered installed and generally “invisible” files in the files app. I’ve called All IPhone that was a contact file.

when i started deleting everything from my phone, all messages and photos and accounts, it became obvious i was signed into the app store in a sandbox account i never signed up for or into. I believe this is one method by device as compromised through apple.

does anyone have any ideas on if it would be possible for a hacker to use my apple pay through some scam developer who had initiated a testing agreement between myself and them?
