Aoa Shariq,
I completely understand what you are going through. but the reality is that your petition will not be beneficial for any of the aspirants including yourself. since you have consumed your three chances i suggest you to give up CSS, since it is a game of luck and gamble, and move on with your life. i am sure there are many other professions in which you can excel. even if there has been mark deduction policy , i do not think that you will be able to prove it.
consider it as a brotherly advice
