Q: How do I get a refund for iCloud storage (downgrading) ?

Hi there, saw my annual iCloud storage billed yesterday and went to downgrade and get a refund. Couldn't find any links(s) that spoke clearly and concisely on how to get a refund. My iPhone says to contact support for a full refund within 45 days. Used iTunes and "reported a problem" with the storage purchase but was routed to the wrong customer support team who then suggested I seek support through iCloud. Well there's lots of topics and associated links - none for a simple refund. Any help (preferably a working link that takes me right to the correct form screen to submit my iCloud storage refund request) is greatly appreciated.

Cheers!
