Terminating an annual ticket early in Vienna?

Hello, Does anyone have experience terminating an annual ticket early in Vienna? I know I'll have to pay a 22 euro fee. But it's not clear if I have to go in person. This cancellation page kind of makes it seem like I do but I'm not sure. Has anyone gone through this?
