Hi Nikhil,
I periodically see cases where people have had their plans destroyed
by an an agent and all I can suggest is that if you want to make a new
application with a reliable agent then it's going to depend on the
paperwork and you'd certainly need to do a Freedom of Information
request at the outset to identify what lies were told and what you
signed. As a general rule, always make sure that your agent is
registered with the MARA and never sign anything that isn't true to
your knowledge. In your case DIAC would not hesitate to say that you
were of bad character if you have knowingly signed false documents.
Cheers,
