As this is the only way of having an answer from 7 cumes I would like to add that at the end of the activity you agreed that it didn´t go well and that you were thinking on somehow compensating us. I would also like to mention that we are only trying to have part of our money back since the service was not good and not fully provided. I could list several other things that didn´t go well beyond those mentioned by Jorge but I really don´t think I should do it here. Nuno, you are perfectly aware of what went wrong and why we are asking part of our money back. We have no doubts about your good work in other activities but we really think you should have the sincerity and humility to admit that this specific activity went wrong.
