Is this ethical? HyperVoice by TaskAGI lies on their T&C

Hypervoice by TaskAGI is a TTS service. When you pay money and subscribe, both the terms and conditions and the refund policy state that upon cancellation of the subscription, you will retain your access until the end of your billing period. But as seen in image 1, the moment you go to turn off auto renewal, you are faced with the big orange warning and the moment you click confirm to unsubscribe, all your tokens are confiscated and all access to paid features is revoked - even if you have a full billing term ahead of you.
