There is no -ve response/ +ve response...There is no response to CSE from NDVO asking for status update...
..In fact once u raise CSE u will get an auto-reply saying they will not respond to queries asking for status if the File is within Normal processing timelines (which for NDVO is 24 months see here->

So raise a CSE if u wish but do not expect to get a reply..I'd advise applying for GCMS Notes instead..
5000 rupees
..ur Consultant is looting u...Yes he is talking abt GCMS Notes...it costs CAD 5 in case u have a relative in Canada and CAD 25-30 in case u don't have a relative in Canada and want to apply through a 3rd party website...
