I’ve already locked out and canceled every subscriptions,but the device has tried to cut my money.

Greetings, Yanynn!

Thanks for reaching out to the Apple Support Communities! It sounds like you've cancelled your subscriptions and are still being charged by iTunes. I recommend checking out this article to Change your subscription plan and be sure there are no subscriptions currently active.

If you see no subscriptions and have made sure third parties are not billing you for subscriptions and still have see charges, I suggest checking out this article If you see 'itunes.com/bill' or an unfamiliar charge on your statement for the next steps to take.

Take care!
