BSNL Dataone — dataone ID is not operating to check net usage

We have dataone broad band connection at home last 2 years. I can't check my usage. They created & gave me one user ID & password, I configured my modem with that, It is working with very low band width speed. The same user Id & password must be use for Dataone mail & net usage. But that ID & password never open my mail & never connected to net usage. I can open web mail ( bsnl.in). I don't understand, this id for dataone.in, but it is working on bsnl.in. Is this is wright or wrong. I wants to see my net usage, any one have to help me.
