get onto your dealer mate. they are jerking you off. you should have at least a build week by now, or even a delivery date. hassle them daily till they get f7cked off with you calling you and they'll get their a7se in gear.
Well, wouldn't ever suggest not giving the dealer hassle but...
I ordered (GTD though) about the same time and have (still provisional) build week 45. Dealer showed me his order list couple of weeks ago - roughly 15 Golfs of vastly different specs all without confirmed build weeks after 2-3 months. From what he said, it's pretty much luck of the draw if an order goes through quickly - some speculation that they're prioritising euro-zone orders given the exchange rate but in no way confirmed!
Ordering from a larger dealer network (my case) may also not help you. Be thankful you don't want a 1.4 TSi - I've heard six months lead time on that engine!
TBH, when you see that orders are up 40% year-on-year and that the Golf is now biggest seller in Europe you're probably just creating stress for yourself worrying that other people are getting cars quicker! OTOH, if the dealer hasn't even given you a provisional build week then I'd be worried!
