I have similar case. I received COPR and visa stamp in February and got married in April. I raised CSE and sent e-mail to visa office after two days (sydney in my case) from CSE, i received reply that i have to contact Visa office. and visa office sent a generic e-mail with links of different type of application and also it was written that if your required answer is in the links then you won't get any further reply. now i'm confused that will i get any further reply or no. i couldn't find my required details in that e-mail.
