My in app purchase tells me there is an error in purchasing the upgrade, even though I have sufficient funds. Why is this?
I was given a $15 gift card, but as a South African, could not use it in the local I tunes store. I changed my address to an American one, which let me upload the gift card and browse the US store, but when it came to buying an app or purchasing an in-app upgrade, it told me there was an error and I should get support.
Any ideas?
