Randomly been charged for apps.
I was looking at the top charts, in the free section, and I saw that both iPhoto and iMovie were there. Normally, they were £2.99 each. So I downloaded both. For 3 days, it was fine, and my balance was unchanged. Then, today, I saw that my balance had gone down by £5.98! So Apple had charged me for apps that were free. Does anyone know how I can contact Apple to rectify this mistake, and is it just me that this has happened to? I really need help!
