Well, we don't actually know you, and haven't read your publications. All we can judge your work on is the posts you have left here... which actually contain grammatical errors ("I spent enough efforts and time", "the problem does not rely there"...), so... it should not be surprising that we are suggesting writing as a possible cause. Likewise, your NSERC reviewers have not read your publications; they only have your application to go on.
We are just trying to help, because you asked. Please don't take out your frustrations on us.
