They tried a bunch of times to do so.
At one point they sent an email and a letter saying they'd come next month (I think sent May for a end of June arrival) to do the interview. The door stayed locked. The embassy sent a letter back saying they declined the request... in December. That's right, 6 months after the letter was sent, 5 after the date concerned, they said 'no'.
So don't talk crap, eh? Wikileaks may claim it, doesn't make it true.
