[Resolved]  South Western Railway — tatkal quota

I travelled from bangalore to madural with an e ticket, PNR no [protected], train no 0689, on date 6th sep. The ticket was purchased under tatkal quota as at the time of reservation it was indicated that in other quotas tkt was not available.
On reaching the train and travelling upto madurai i found out nearly 30-40 % births were vacant and the chart also confirmed the same.
I wonder why I was not allowed to reserve under normal category when so many births in my coach[S7] were vacant. in my cubicle itself against 8 births only 4 were occupied from bangalore to madurai. On arrival at madurai when enquired with other coach passengers they also said many births were vacant all thro the travel in their coaches also.
I am shocked at the way I have lost my money and I wonder who is responsible for all this malpractises/lapses
Why should i loose tatkal charges when that was not warranted.Is the Indian railways become another money maker by cheap cheatengs?
Is not me am entitled for refund appropriate?.
