My opponent left, I waited 29 min

I believe it was explained to the OP:

@Interestinggame

I contacted the moderator so that he have a talk with him/her. He told me he was going to anull it, to which I refused.

The reason for annulling this game has nothing to do with the opponent escaping however: it was annulled to prevent distorted ranking, since the game was (a) not yet decided and (b) the player with the better position had lost the game. So it’s to prevent the Black player from being ranked too low and (possibly inadvertently) sandbagging.
