Only the department can assist. I am unable to tell you what is going on as I am not with them. The fact you have not had a letter rejecting you means that they are still dealing with it.
If they ask you for more information then the application is not complete.
If they are still taking too much time then you can take it to the AAT
But you have to talk to them I am sorry to say.
I hope this makes sense and is of assistance.
If there is nothing further
thank you for using my services.
If I have missed anything, or you have any further questions please let me know
If there is anything else in the future please do not hesitate to ask.
Please do not forget to leave positive feedback.
