It is a translation gig, if someone sends me a terribly written, english guide to quick loans i am not gonna write new content because it repeats itself unnecessarily etc.
You are not supposed to write new content. However translating is RE writing. So if the original is crappy a translator IS supposed to take the meaning out of it and make it a decent text in his language without excluding informations.
If it is poorly writting you are not supposed to stick with it.
Then again these feedbacks could have been given by anyone. I strongly suggest to find a dane on the forum that can corroborate what you are saying if you hope getting hired here.
And if you are really good, I wonder why you get through the trouble for 15$. I know how much times it takes to do a good translation of 1k words, and given the living cost in DK, 15$ is just a complete waste of your time, hence the suspicion.
