He might have requested docs from you, and once he does that job,
they put your file in the queue again,
He is very good, he used to be my CO,
If he sent you the docs with his signature at the below, you will find his telephone number, give him call, and he is very good on giving answer
I always have spoken to him, he picks up call straight away, compare to calling IMMI and wait for 45 mins
All the best..
