So..looks like there is a trick you can use. We had been looking for appointments in chennai for week of nov 19th and nov 26th for over a week now. We were growing anxious since the only these 2 weeks are not shown. So, from reading one of the posts, we picked language of appointment to be non-english and were able to see wide open dates for this duration. I know it's probably not right to use extra resources (there will be a translator I suppose), but I would much rather have an appointment. I sure hope it's works out ok. Buyers beware!
