Irctc — Failed to book ticket - SBI Internet Banking missing from Banks List

Address: Patna, Bihar

Today I tried to book tatkal ticket from IRCTC. I have to travel to Delhi, but I felt deceived by IRCTC. After filling all the details when I went to make payment I was shocked to see that the name of SBI was missing from the list of Internet Banking Banks. I failed to book ticket. I contacted my Bank (SBI) & came to know that SBI has nothing to do with website of IRCTC & the site is maintained by IRCTC. Why the name of SBI was missing? Is it done deliberately by IRCTC for some personal gains??? Please clarify, why the name was missing from the list. Most of the people who had tried to book tatkal ticket today through SBI internet banking, would have failed to book.
