I had travelled from VPT - SBC on 1st January 2012. There was an AC failure throughout my journey time and the TTE agreed to refund the difference amount between SL and 3AC, and gave me a receipt for the same. Being an e-ticket, I filed for TDR on 2nd of January,2012 and now the status shows "TDR Status: CCM Registered". Any idea how much does it take? Anything apart this, am I supposed to do? Any info would be of great help. Thanks. Prasad
