Indian Railways — About their pathetic and non secure service

I booked an e-ticket through irctc and the pnr number of the ticket is [protected]. I initially booked 4 tickets and later on i cancelled one out of 4. Today when my parents were traveling through the ticket, a TTE came and said all the 4 tickets are cancelled and the money has been returned to the card. When i checked the pnr status online it showed me that 3 seats have been alloted to my parents(couch SE1 and seat # 57, 58, and 60). I spoke to TTE through mobile phone(which my parents were carrying) and he said all the tickets are cancelled. I said please check in the chart and he said "I have given those seats to some one else and if i have some vaccant seats then only i will give seats".

I paid the full amount whatever i was suppose to pay then how you guys can trouble passengers.

I called up 139 and explained the whole scenerio and asked them for an immediate help but they said they are help less.
