Irctc — Cancellation of TDR

Address:

Hoshangabad, Madhya Pradesh

I have by mistake submitted TDR for wrong ticket and I could find option to cancel TDR.Request you to cancel tdr or let me know the process for the following Reference number -ekt[protected] and pnr number is PNR Number: [protected].
Also I want to change reason for valid TDR Reference No: ekt[protected] and pnr is PNR Number: [protected] and the reason for cancellation was that only one ticket of the traveling passenger was confirmed and other two were in waiting list and I could not cancel the ticket a day before because chart was prepared from some other location and ticket was not confirmed till that time.
