I think nobody has received any letter. There were total of 6 guys in subjective test, I was among them. I hope you were there as well for as you are asking about it now. That's makes two of us. 3rd one I know as well, he was asking the same question here a day ago. So if 3 out of 6 haven't received any letter then I believe either only the remaining 3 were called or our letters aren't dispatched at all. Else God know, that's my guess.
