Guys, you can only ask so much from any visa office but chc has already given him a huge favour by asking him to send his IELTS separately coz you are suppose to send all your docs together. Even if he tries to send written explanation that still means that immig officer has right to either award points for that or not to award any points without asking any further docs. I believe that if you dont score minimum of 67 than your application will be refused without any leniency. Any letters of consideration won't do the trick. Only option is if you can reappear in IELTS to improve score and it to CHC. They might consider that, who knows........
