I put my wife’s debit chime card on to my account today After I had to take my chime card off because when I put her card on Apple immediately took $9 of her card and we don’t know why. I never purchased anything for it to do that? Also I did it before with a different card which was mine a chime card as well and it did the same thing? Please help me and refund all deposits took from both accounts if you can? Please and thank you I did everything I could think of and went through deleting anything that could charge the account and undescribed active description and now out of options. Pls help
