Zerodha,
you have understand that when the issue comes, traders first job is to reduce his risk at that point. He will not have the time to even think he has to send an email at that instance and once the 'event' is over , he will not bother to send email. He will have to try and restart his terminals and get things moving.
Hope you understand this, just because people don't email/call the same issue doesn't mean they don't have it.
If this was the case i would send you at least 10 emails everyday , but i don't have the time for it. Also this common issue has been pending for months now, so most people including me don't bother to email.
