Hi Khilo
I am not going through the Cairo VO... but after being on here for the last 7 months... there were some issues with the November applicants getting their SA... so a lot of December applicants received their SA before applicants from November
Not sure if you were one of the unlucky ones as you don't have your timeline posted.
If your application didn't get to the VO in Cairo before the December applicants did... that could be the problem
However that being said... Applications don't seem to be processed in order of receipt... Everything tends to be random when it comes to this process
Good luck and hopefully you will hear something soon
