The best approach is to finish up the quota of the current plan and then purchase a higher plan from our official landing page https://aiwisemind.com using the same email address to keep all subscriptions under the same AiWiseMind account.
And if the older plan is not required anymore then you can cancel it from your Warrior+ Account before it renews again. You can also manage your subscriptions from the https://app.aiwisemind.com/my-profile page.
Or you can just let us know, and we’ll do it on your behalf by issuing a support ticket.
