Q: UNAUTHORIZED CHARGES TO MY BANK ACCT

I'm not sure what a triple charge is, but you can contact iTunes support for assistance. http://www.apple.com/emea/support/itunes/contact.html

Is this just a small amount on the card? It could be verification of the card if you were making a purchase. iTunes Store charges on credit and debit card statements - Apple Support

OK.

You should do that.

Try looking at your purchase history and seeing what the charges were.  You could then contact iTunes support if need be.

What question do you have?   

While in iTunes, make sure you are logged into your account and then go to Purchased. If that doesn't help enough, you can log into your iTunes account and go to Account. Then there is a section for Purchase History, and a link for See All.
