Thanks, I am so angry, I told them I don't smoke (ex-smoker) and when I wrote and asked for the evidence, I told them if they had evidence, if was not from my room so either they got the wrong room, date or the evidence was planted. CRS replied and said it was in my room, and they don't plant evidence but they must do as it was not mine.
Don't know if I should write back or just ignore this second letter.
