Irctc — Forgot user id and password for irctc account

Address:

500017

I was registered with IRCTC. I forgot the User Id and password for the same .
When Iam trying to open a new User Id Iam getting a message that my Mobile No has already been linked previously. As such Iam unable to open a new User Id. I would like IRCTC to either inform my User Id and password or delink my Mobile No linked to the old User Id to enable me to open new User Id.
