Refunds for multiple accidental purchases

Hiya, I was buying a replacement airpod for my friend, and when I got to the “review repair” stage there was no button or anything to confirm the transaction, so I went back and forth several times. Someone from apple support ended up replacing the airpod for me on her end, but i’ve been charged for an airpod 5 times. I’m just wondering how I can get this money back?

Thanks
