Indian Railways — tdr filed was cancelled and no response from [protected]@irctc.co.in

Dear sir,
I have bookef 2nd ac ticket and was confirmed but the day of travelling, no 2nd ac coach was attached with the train. I was askef to travel in 3rd ac where as i have paid 2nd ac fair. Tdr filed was rejected stating non receipt of tt certificate. I attached the same in email and send to [protected]@irctc.co.in and received tocken no irctc #6920893. Several mail sent after this but no responce from irctc. Every time new tocken number auto generated but no responce. No option available to re fill tdr again. Its a cheating i can say as all these are done intentionslly to make money. No care to the passenger travelling in rail.
Best regards
