They usually do not reply to CSE if the normal processing time has not elapsed, you should receive reply to CSE that you will raise after 29th November 2015.
GCMS is very helpful, probably the consultant does not have the capabilities to read GCMS notes hence he/she doesn't want you to order them. You must order them now to get some idea about the processing of your file. If you need any help with deciphering the notes, there are plenty here that can help.
I suggest you raise GCMS notes immediately.
