Your Purchase Could Not Be Completed
Hi. I am getting this error and the message "For assistance, comtact iTunes Support at..." when trying to buy an App in the App Store. That's all. The iTunes site does not have any information about how to fix this issue. I just want to buy an App! It shouldn't be so freaking difficult.
