Thanks for the reply. I had the impression that they have quite the back log of stage 1 applications right now and are very stretched. In my own experience they have been very good at providing any sort of feedback. Even if it can take a little time they come good. It took me about 6 months to get feedback when I failed my stage 3, but it was very very good feedback and was definitely worth the wait.

I most definitely agree with this. I will give them plenty more time to get back to me. In the mean time I shall remain patient and will not get overly concerned.
