Getting removed from a broken tournament

I have been “in” a tournament for almost a year now. It was a regular live 9x9 tournament. It wasn’t going very well for me (I was playing very poorly, honestly), so I actually dropped out of it entirely. However, the tournament seems to be broken, and still shows up on the list of tournaments I’m in. I’d really like to have this tournament removed, as it has now been basically a year. How can I make this happen.

Here’s the link to the tournament, if it matters:
