Billing

I was purchasing a song on iTunes which costs US $0.49 but what was deducted from account was more than US $34. I’ve not received a receipt in my email to show the transaction details of such billing and I’ve not been refunded.

secondly I was purchasing a song on iTunes right now but it brings the message that transaction is declined. I’ve topped up my account and when I try to purchase it brings the same message and when I update my billing details still it’s declining the purchase.

The bank told me to contact iTunes because on their end my account is fine.

kindly assist.
