yes its sort of helpful. Just click the link and a form appears where you fill in the required info and at the end there is space to write your query. Just send it and they do reply back. This is how i got my file number from CHC-I and i also asked them through the same link if i could send them updates voluntarily and they replied that it would be good if i did so that they had more to go on when my file gets in to initial review (our consultant advised other wise though) any way a few days back i emailed CHC-I on the same link coz i wanted to confirm if they had updated my new address in my file..the auto reply i got was that if my question was regarding address change update it will not be responded to. You can try i hope you get some response takes about 10-15 days to get a reply...
