Yes, u r right. The consulate people are really obnoxious. One day when I checked with her about my packet. She asked me - why I was wasting my dollars and her time in calling her repeatedly. Anyway, since we have no other go we have to tolerate it.
About Lister labs:
I think we donot need any appointment. I was born and brought up in Chennai - so I am quite sure that for any testing in Lister Labs you need not fix an appointment. Anyway, I am planning to ask somebody from Chennai to check on it. Only criteria is that if you go for the test before 10:30 a.m., your results will be given on the same day by 4:30 - 5:30 p.m., otherwise, I think you will have to go for the results next day. This is the normal rule there - I have undergone some tests in that lab. But since it was done a long time back I am not so sure. I will get the info by this weekend on whether we have to fix an appointment.
