What about what I did not choose to buy?
I did some research, by the way, and Android phones offer a full refund, no questions asked, if it's less than 2 hours since you purchased an app and you've never refunded that app before. Which would have easily solved my issue.
Make what excuses you like, but I was not trying to get anything for free. I was simply trying to do what every physical store allows you to do with no issue - put something back on the shelf because you can't afford to get it.
The physical store equivalent of what Apple is doing would be if someone brought stuff to the front desk, didn't have enough money, and the store proceeded to hold the excess items and refuse to let that person back in the store until they bought those items. Which is just utterly ridiculous.
I think you should take a good hard look at the company you're making excuses for. Just because it's an electronic purchase instead of physical one doesn't mean a company should get away with screwing people over.
