State Bank Of India [SBI] — Account not mapped to my net banking username

Address:

Krishnagiri, Tamil Nadu, 635120

Dear sir,
I got my net banking activated on my home branch before 3 days. I was able to login and do all necessary stuffs. When i was done with that i got a message that states no account is mapped to my username. When i checked about the same online i saw some similar problems that asked to unhide the account in manage account option. But when i got to manage account and unhideing option i had no account hidden also. It would be very convenient if you would clear my doubt regarding this.
Thank you
