If you and your brother use the same ip you can't really prove to toonslab that your brother's acc isn't just your alternate.

Honestly, if you think about it for 2 mins, you might wonder, "Hmm... Am I the only one having this problem with the bans?"

There could be a lot of people thinking that their hours aren't passing by, unless they stay on the app.

Maybe the people who review the bans decided to just auto-respond with a message towards the majority of the complaints, which is "I didn't do it!"

And they have probably gotten the lesser of feedback from "My hours aren't reducing, help!", so they kept the same auto-response.

Doesn't mean they don't care, or have no interest in your message. They probably just need to confirm the problem, and fix it.

What do you want them to say? "Thank you for notifying us, we will fix this soon"? Give it time.
