If you got charged for the subscription immediately, it could be because you had a subscription with us before and already used the trial. When you reactivated your subscription - you got charged immediately for the full weekly plan.
It is also possible that you selected an immediate discounted subscription which doesn’t include a trial period and is processed on the same day that the account is set up.
If you don’t believe this to be the case - please reach out to our support team who'd be happy to help at [email protected].
