Adjustment of excess paid service tax

Dear Experts,

My company has wrongly paid the service tax twice for security / detective agency service under reverse charge including interest on 25th October 2016, for the month of July 2016. It is not shown in first half year return. Return for the period of Oct-March is not filed. How can i adjust the excess paid amount?. Can i use it for paying April 2017 service tax ?

Thanks

Jerry
