Before you start or upgrade a subscription in RAI, please make sure that you're aware what type of subscription you are starting and how much you will be charged (subscription prices are clearly stated in your contract with Mono). All non-trial subscriptions will automatically be billed by the system and refunds are not possible.
Start your new sites on a Trial subscription if you don't want to be billed. Trial subscriptions are free of charge and can later on be upgraded to a paid subscription. All other subscription types are paid and non-refundable.
