I could not process the refund issue for inadvertent subscription to iscanner

Hi,

You can submit refund requests on reportaproblem.apple.com after signing in with your Apple ID. If you have already done this, the refund was denied, or you have another issue preventing you from using the website, you can also contact Apple Support and request the refund.
