Magic T review for Recharge Subscriptions App

There's absolutely no support. NOTHING! The "Get Help" link in their app is inactive. There's no online chat and there's no ticket system. How does Shopify let them have apps? P.S On October 16, 2023, they replied to my review and I never heard from them. I finally managed to get to a new app and uninstall this app. Supper expensive with no support.
