Southern Railway — money debited twice but ticket not confirmed

Address:

Chennai, Tamil Nadu, 600101

I have booked ticket for 1st ac for travel on 4/06/2018 from tiruppur to chennai vide transaction id [protected] & [protected] on 31st may
The amount debited was rs 1146.8 and another 1146.80
Even though the ticket was available and money debited the ticket is not booked.
Why my ticket is not booked even though the money is debited twice.
Its not my mistake
Now i am getting messages that refund will be done for 1135 in each transactions.
We have spent time for booking these tickets end result is negative.
Also why i should get lesser amount as refund
