How can I cancel a payment?
I recently bought a ringtone for my phone with my friend's itunes account. And then I got back to mine, no problem ever occured until creating another account for myself, and while creating a new one it didn't let me to continue or skip without sharing my credit card information. Itunes made me pay for the ringtone without permission. How can I cancel the payment? (the option for even free ones is always ask, so that is not it)
