Tds late payment interest

Dear Friends, 

       i have received notice from TDS department for late payment interest. while checking i found that i have already paid the interest. however the calculation of deparment is different. the department is calculated interest from the date of deduction. however the department has not given me the credit for the interest amount i have already paid and demanded full interest. now advice me what should i do to get the Credit of interest i have already paid and pay the balance so the default is get cleared.

Thanks in advance
