May I ask if you’ve disabled your billable features, therefrom removed/canceled your subscriptions as follows on the below article?
You’ll need to follow these directions here:
Regarding the refund in general for plans here is the cite:
4.3 No Refunds
FEES ARE NONREFUNDABLE. YOU WILL BE BILLED IN FULL FOR THE SUBSCRIPTION TERM IN WHICH YOU CANCEL AND NO REFUNDS WILL BE PROVIDED FOR THE UNUSED PORTION OF SUCH SUBSCRIPTION TERM. Following any cancellation, however, you will continue to have access to the Paid Services through the end of your current Subscription Term (except with respect to Services subject to usage-based billing). We may, in our sole discretion, provide a refund, discount, or credit (“Credits”) to you in a specific instance, however the provision of Credits in a specific instance does not entitle you to Credits in the future for similar instances or obligate us to provide additional Credits.
