Hi Aliby - where are you based? UK? (Again, I use the caveat of only speakng for UK procedures)
I see you are in the hallowed group of having been passed without corrections - very well done! To be honest, I would have expected you to have received something in writing from your registry/research office by now comfirming this. Admittedly, if you passed without corrections, they don't have a list of them to type up, but you should still get writen confirmation of the outcome fairly promptly (1-2 weeks after viva)
If I were you I would contact yout internal examiner or research office to enquire what has happened. You may have been sent something, that may have gone astray given Xmas, etc.
