You should read the terms more carefully. There's a 45‑day cancellation window — if you cancel within that time, you don't have to wait a full year. It's clearly stated in the rules, which you probably skipped.
Let me repeat this one more time in case you're still confused about what's actually happening.
I subscribed, used it for 30 days, and canceled. The cancellation went through successfully, and I'm well within the 45‑day period — unlike you.
The real issue is different: the site for some reason still thinks August 14 hasn't passed. So it won't reset the quotas, and I can't renew or keep using the service even though I'm ready to pay
