Successful subscriptions do not appear in the sandbox

The problem that I am experiencing is that the subscription is successful even if i try to subscribe once more it will say that i am already subscribed, but if i try to cancel it, in my sandbox account there is no subscriptions.

Not sure it is related but the other issue that i am experiencing is that the webhook is not called
