When will unlimited games be expired?

I have many unlimited games with high winning chances, but it seems my rivals left games forever. What will I do? How can I finish these games?

I think basically there are no unlimited games. There is always a limit, which often is more than one day per move for correspondence games.

Makes no sense to offer Unlimited when it's really 21 days.

The problem is that I dont even know when the last move was made
