Hi! I understand you'd like to cancel your Strum app subscription and get a refund for the last week but couldn't find a way to do it within the app itself. Let's get this sorted out.

Strum provides a self-serve cancellation form that you can use to cancel your subscription and receive a prorated refund for any unused time, including the last week you've paid for. The refund and cancellation are processed automatically and instantly once you submit the form.

Here’s what you can do:

1. Open this cancellation form link: Strum cancellation form
2. Fill out the required information on the form.
3. Submit the form.
4. Your subscription will be canceled, and the refund for the unused time will be processed promptly.

If you have any trouble accessing the form or need me to guide you through the process on your iPhone running iOS 18.7, just let me know! Are you satisfied with this solution, or would you like me to assist further?
