Hello Sandy,
I'm August 25th applicant as well, I too updated my marital status change in March 2016, but they never replied to my email, I sent update through case query in April again...still no response. So, I decided to call CIC on 18th April 2016, when I reported agent that I didn't get any response to my emails from CIC, she went silent and later she sent me detail email to fill out forms and send the package for addition of spouse to Sydney office. On April 22nd 2016 they received my spouse documents and on June 1st 2016, CIC requested medical...police clearances and spouse questionnaire for us.
I submitted all the documents by 21st June 2015 for both of us and after that I never received any update. On 4th nov 2016, I got GCMS notes, where everything is passed and last updated on 15th July 2016 and file location is PACE.
I called CIC as well 10-15 days ago, agent said everything is passed...no additional information required at this time and wait for final e-mail.
Hope to see the miracle this month....15+ months now....no patience anymore
