I just purchased a month subscription for my android about an hour ago and made several different tests. Sorry to say but I am not too flattered. I'd like to get a refund asap.
If you have purchased your Freedome license from the Google playstore, they are the contact point for any refund. You have to cancel the subscription in the Google play store.
I tried doing that several times already and nothing shows up in my subscriptions list regarding your app. I tried closing and opening playstore, tried to Uninstall and install the app, and nothing.
You can check these links here and here for more information. May I know within how many hours did you try to request for refund after you have purchased the license?
