Thanks for reaching out to share your feedback on this! As you're on the Easy Savings plan, the addition of a normal Bank Account would've, indeed, resulted in this charge. As Geoffrey mentioned, other users have also complained about the lack of notification here, which is something we'll take into consideration moving forward!
Unfortunately, as the account was created with the subscription over a month ago, and you've already made deposits to it, we won't be able to refund the invoice. However, if you delete the account and reach out to support, we can make sure you're not invoiced for this again, next month π
