I think you mean lose, not loose.
It sounds like you lost a rated game, based upon lag ,and with this loss your rating dropped ten points. Is this correct? (You don't lose points based upon "moves.")
To my knowledge, this server doesn't compensate for players with lag. It doesn't have timestamp/timeseal, or anything equivalent, nor are games ever adjourned when one player has a connection problem.
If these things are important to you, one option is to play online chess at other chess sites that offer these features.
But yes, I agree with you. It's no fun to lose a game through no fault of your own.

How can I loose 10 points on one move ?
when the internet is trying to load the page.
There should be a way to challenge such a decision.
