I think you just learned that unspoken promises are worth the paper they're printed on. That said, the iTunes Store Terms and Conditions clearly state: SERVICES AND CONTENT USAGE RULES [...] All Services: [...] - It is your responsibility not to lose, destroy, or damage Content once downloaded. We encourage you to back up your Content regularly. [...] REDOWNLOADS You may be able to redownload previously acquired Content (“Redownload”) to your devices that are signed in with the same Apple ID (“Associated Devices”). You can see Content types available for Redownload in your Home Country at https://support.apple.com/en-us/HT204632 https://support.apple.com/en-us/HT204632. Content may not be available for Redownload if that Content is no longer offered on our Services. So next time, I suggest you read the T&C before you buy something.
