Being charged for no reason...

I was just charged by Apple iTunes for $10.59. My credit card information isn't even on my iTunes account. I had deleted it when I thought someone hacked into my account. I could not access the iTunes store so therefore I deleted it. I reset my network settings and now I am able to access the iTunes store but now I have been charged. I want the money put back into my account. I did not purchase anything from the store. The only thing I had set up for automatic pay was my netflix, but I disabled that. So I have been charged for no reason.
