I received my Class 2 assessment after 4 months. I personally went to the DGCA office once, but my assessment was not ready and the doctors were on leave, so there was nothing I could do except getting my file number.
I kept calling them but all of my efforts were to no avail. Even if someone answers your call, you won't get any useful information. They'll tell you to call the next day and the same thing repeats again.
So I just waited patiently and one day the assessment arrives by post bringing a big, bright smile on my face.
