fraudulent charges to my iTunes account
I am being charged to my iTunes account for items I did not know about and not approved. I wish to receive a refund for fraud charges, change my iTunes account name and password. I am contacting my bank credit card, but want to ensure that I can received a refund and that no future charges will occur. What solutions do you have since, I'd guess, that this is not new to iTunes?
Thank you kindly
