To change the date of your recurring monthly payment, you will need to cancel your current subscription first before it charges you on the current renewal date. Once your subscription expires and your account turns to Free, please don’t worry! You will still have access to the service and all of your playlists will still be available on the application. However, offline mode will be disabled and you can only play the downloaded songs when you are connected to internet.
The next step is now choosing the date when you would like your payment method to be charged each month and then subscribe again to Anghami+
