Indian Railways — extra charges

Hi,
I was travelling to Lucknow from Ghaziabad on 20th of March. Due to non-availability of tickets I took general ticket and while boarding the train no. 15910 It was too crowded any how I boarded to the train via pantry gate. The TT was standing in front of me and asked to show ticket which I have shown him on his request. So he asked me to make sleeper ticket for Rs. 360 which I have paid him in cash. I was already owing the general ticket and the amount for sleeper ticket is Rs. 280. Neither he deducted the sleeper ticket amount from Rs. 360. Kindly help. Attaching the Receipts.
