Hi Isidro,
Possibly there is an issue with the translation, but I don't understand what you're asking. You've appealed this model several times and have received consistent responses. If you'd like further explanation for why we made the decision on which Concord to accept, you may appeal again and we will make another attempt at the explanation.
Otherwise, the forum is not the appropriate place to appeal a judgement.
I hope this helps.
Alex
