If you haven't got a "more time needed" or a request for more info email from Apple, and it's 2 months already, I would be tempted to reject the binary, submit a new version of the app, and start waiting for review all over again. Make sure you haven't misplaced or lost any email or calls from Apple saying that they are waiting for something.
There's a firewall preventing you from contacting any reviewers, and that's on purpose. As it is, most apps take about a week or two in the queue. If 100k+ developers kept calling and bugging them about all their apps (and they would), the reviewers would get zero reviews done, and the queue would grow to be months/years long for everybody.
