Irctc — "Unable to complete transaction. Please try later" - Error shown

I tried booking a ticket on a heavy traffic train. But the money from my bank got debited and still the transaction got failed. After that I got "Unable to complete transaction. Please try later" - Error shown each time I tried to book another ticket. This happened between 10:00 AM and 10:30 AM. If this happens, then how will ordinary people with urgent issues book a tatkal? Moreover is IRCTC doing anything for the same? So many agents are booking tatkal and selling at double rates. But the ordinary middle class is unable to use this tatkal. Someone has to take care of this issue. Millions of them are complaining and the issues are still there.
