 Cheers, Tom

I do not know why I have been charged $10.59 on my mastercard for the past three months.

Well, neither do I. You can see your purchase history like this See your purchase history in the iTunes Store on a Mac or PC - Apple Support. It should include those charges. Since it's periodic, you probably subscribed to a TV program or software program. If it's an iTunes charge, the previous post here covers all the contact possibilities. And remember, we're just other users here, so we can't do anything about your accounts.

Thank Tom - this is extremely helpful.  I have several charges that just came through on my apple / iTunes account that are non iTunes, App related.

Cheers,
