Q: I have unauthorized charges on my bank statement - I need them reimbursed immediately!

Do they show on your account(s) purchase history ? If they do, and nobody else has access to your account and/or devices/computer, then to contact iTunes Support : http://www.apple.com/support/itunes/contact/

If they don't show then contact your card issuer

I have itunes charges on my bank account that I cant identify?  Please advise!

Have you tried looking at your accounts purchase histories : See your purchase history in the iTunes Store on a Mac or PC - Apple Support ? And family members accounts if you are a family organiser in family sharing ?

I have three bank charges this week! How do I reverse these charges and get this closed.

Since Apple is not here. You will have to contact Apple rather then posting here. Try using the icon in the lower right hand corner of this screen label Contact Us.
