Go to bank where you deposit service tax challan amount and rectify it.

Dear pankaj

Its happened on 2009-10 IInd Half year .But now i think its not possible

Than you should write a letter to AO of central excise superintendent with a zerox copy of challan.

Go with letter and you can ask this query to service tax help desk.
