That said, you are fully entitled to post a negative review of your experience. Noone has challenged that.
What people are trying to tell you is that it is common and documented knowledge that sending a watch back is a gamble. So is buying a counterfeit from China over Internet.

and the repair cost me 2000€
So, your expectations are simply not right.
