Unrecognized Charges for iTunes

On May 15, my card was charged for:

• 7 iCloud subscriptions
• 2 × €17.99
• 1 × €11.99

All charges were listed as apple.com/bill IRL iTunes.com. I only use the 200GB iCloud plan and did not authorize these purchases. Support previously said they’d be refunded, but the funds were withdrawn. I have screenshots confirming this.

I’ve removed my card. I never shared my details. I was told to call, but I’m in Serbia and can’t afford international calls. I’ve already lost money — I won’t spend more to fix Apple’s mistake.

I need a full refund and a resolution via email or chat. Should I stop using a card and switch to gift cards to avoid this in the future?
