How do I report a wrong puzzle?

Solution is wrong. I found a better move which the server doesn't accept. I want my rating back.

Your move is much worse

After 1.Nh3 gxh3 2.Qxf3 I am threatening mate on h1. Do you see any defense?

Yes kf1

Yes, sorry for some reason I thought the Rook was on f1

It would be interesting to find out if there has, ever, been a 'broken' puzzle on this site.
I'd say, there has not.
