I have lodged my SMC application on 26th April 2016. It is almost 10 months and still waiting for a decision. I had last contact with my CO on 9th December and he said I am still processing your application. I am trying to contact him again for an update but he is not picking up the phone and not replying to my emails as well.
I contacted Immigration call center today and they said SMC usually takes 6 to 8 months and you have gone past that time frame. If you want we can give you CO's Manager's no and you can talk to him.
I am kind of confused should I talk to his manager? If I talk to his manager is it gonna have any adverse effect on my application?
So far I have contacted my CO around 10 times and he always says I am very busy.
