Question: About my battery repair callback
So I was doing a battery replacement callback on Apple's website, I had entered the device info and visa card, at this point I accidentally clicked back but I had not confirmed the order yet. It took me 40 euros to visa authorization hold! I made new order and I successfully printed my order confirmation and got confirmation email about that. So now I have one extra visa authorization hold on my visa card! How do I cancel this?
ALSO, can I cancel the whole repair replacement at this point and get all the money back? I have not send my phone to Apple yet. I heard that it would be easier to just go in to a local store and change the battery there and Apple might not change my battery if it doesn't have any problems. Much mistakes made today, can someone please help?
